+ * This driver is a fairly straightforward GPIO driver for the

+ * Kirkwood, Discovery, Armada 370/XP). The only complexity of this
+ * driver is the different register layout that exists between the
+ * non-SMP platforms (Orion, Dove, Kirkwood, Armada 370) and the SMP
+ * platforms (MV78200 from the Discovery family and the Armada
+ * XP). Therefore, this driver handles three variants of the GPIO
+ * block:
+ * - the basic variant, called "orion-gpio", with the simplest
+ *   register set. Used on Orion, Dove, Kirkwoord, Armada 370 and
+ *   non-SMP Discovery systems
+ * - the mv78200 variant for MV78200 Discovery systems. This variant
+ *   turns the edge mask and level mask registers into CPU0 edge
+ *   mask/level mask registers, and adds CPU1 edge mask/level mask
+ *   registers.
+ * - the armadaxp variant for Armada XP systems. This variant keeps
+ *   the normal cause/edge mask/level mask registers when the global
+ *   interrupts are used, but adds per-CPU cause/edge mask/level mask
+ *   registers n a separate memory area for the per-CPU GPIO
+ *   interrupts.

-/*
-    History of this driver (Steven Toth):
-      I was given a public release of a linux driver that included
-      support for the MaxLinear MXL5005S silicon tuner. Analysis of
-      the tuner driver showed clearly three things.
-
-      1. The tuner driver didn't support the LinuxTV tuner API
-	 so the code Realtek added had to be removed.
-
-      2. A significant amount of the driver is reference driver code
-	 from MaxLinear, I felt it was important to identify and
-	 preserve this.
-
-      3. New code has to be added to interface correctly with the
-	 LinuxTV API, as a regular kernel module.
-
-      Other than the reference driver enum's, I've clearly marked
-      sections of the code and retained the copyright of the
-      respective owners.

-   Basic firmware description. This will remain with
-   the driver for documentation purposes.
-
-   This represents an I2C firmware file encoded as a
-   string of unsigned char. Format is as follows:
-
-   char[0  ]=len0_MSB  -> len = len_MSB * 256 + len_LSB
-   char[1  ]=len0_LSB  -> length of first write transaction
-   char[2  ]=data0 -> first byte to be sent
-   char[3  ]=data1
-   char[4  ]=data2
-   char[   ]=...
-   char[M  ]=dataN  -> last byte to be sent
-   char[M+1]=len1_MSB  -> len = len_MSB * 256 + len_LSB
-   char[M+2]=len1_LSB  -> length of second write transaction
-   char[M+3]=data0
-   char[M+4]=data1
-   ...
-   etc.
-
-   The [len] value should be interpreted as follows:
-
-   len= len_MSB _ len_LSB
-   len=1111_1111_1111_1111   : End of I2C_SEQUENCE
-   len=0000_0000_0000_0000   : Reset command: Do hardware reset
-   len=0NNN_NNNN_NNNN_NNNN   : Normal transaction: number of bytes = {1:32767)
-   len=1WWW_WWWW_WWWW_WWWW   : Wait command: wait for {1:32767} ms
-
-   For the RESET and WAIT commands, the two following bytes will contain
-   immediately the length of the following transaction.

-   Basic firmware description. This will remain with
-   the driver for documentation purposes.
-
-   This represents an I2C firmware file encoded as a
-   string of unsigned char. Format is as follows:
-
-   char[0  ]=len0_MSB  -> len = len_MSB * 256 + len_LSB
-   char[1  ]=len0_LSB  -> length of first write transaction
-   char[2  ]=data0 -> first byte to be sent
-   char[3  ]=data1
-   char[4  ]=data2
-   char[   ]=...
-   char[M  ]=dataN  -> last byte to be sent
-   char[M+1]=len1_MSB  -> len = len_MSB * 256 + len_LSB
-   char[M+2]=len1_LSB  -> length of second write transaction
-   char[M+3]=data0
-   char[M+4]=data1
-   ...
-   etc.
-
-   The [len] value should be interpreted as follows:
-
-   len= len_MSB _ len_LSB
-   len=1111_1111_1111_1111   : End of I2C_SEQUENCE
-   len=0000_0000_0000_0000   : Reset command: Do hardware reset
-   len=0NNN_NNNN_NNNN_NNNN   : Normal transaction: number of bytes = {1:32767)
-   len=1WWW_WWWW_WWWW_WWWW   : Wait command: wait for {1:32767} ms
-
-   For the RESET and WAIT commands, the two following bytes will contain
-   immediately the length of the following transaction.

+	range 1 255
+	help
+	  Maximum number of DVB/ATSC adapters. Increasing this number
+	  increases the memory consumption of the DVB subsystem even
+	  if a much lower number of DVB/ATSC adapters is present.
+	  Only values in the range 4-32 are tested.
+
+	  If you are unsure about this, use the default value 8
+
+config DVB_DYNAMIC_MINORS
+	bool "Dynamic DVB minor allocation"
+	depends on DVB_CORE
+	default n
+	help
+	  If you say Y here, the DVB subsystem will use dynamic minor
+	  allocation for any device that uses the DVB major number.
+	  This means that you can have more than 4 of a single type
+	  of device (like demuxes and frontends) per adapter, but udev
+	  will be required to manage the device nodes.
+
+	  If you are unsure about this, say N here.

+ *
+ * @adr:		I2C Address of the DRX-K
+ * @parallel_ts:	True means that the device uses parallel TS,
+ * 			Serial otherwise.
+ * @dynamic_clk:	True means that the clock will be dynamically
+ *			adjusted. Static clock otherwise.
+ * @enable_merr_cfg:	Enable SIO_PDR_PERR_CFG/SIO_PDR_MVAL_CFG.
+ * @single_master:	Device is on the single master mode
+ * @no_i2c_bridge:	Don't switch the I2C bridge to talk with tuner
+ * @antenna_gpio:	GPIO bit used to control the antenna
+ * @antenna_dvbt:	GPIO bit for changing antenna to DVB-C. A value of 1
+ *			means that 1=DVBC, 0 = DVBT. Zero means the opposite.
+ * @mpeg_out_clk_strength: DRXK Mpeg output clock drive strength.
+ * @microcode_name:	Name of the firmware file with the microcode
+ * @qam_demod_parameter_count:	The number of parameters used for the command
+ *				to set the demodulator parameters. All
+ *				firmwares are using the 2-parameter commmand.
+ *				An exception is the "drxk_a3.mc" firmware,
+ *				which uses the 4-parameter command.
+ *				A value of 0 (default) or lower indicates that
+ *				the correct number of parameters will be
+ *				automatically detected.
+ * @load_firmware_sync:		Force the firmware load to be synchronous.
+ *
+ * On the *_gpio vars, bit 0 is UIO-1, bit 1 is UIO-2 and bit 2 is
+ * UIO-3.

-	  the Nebula cards, the Pinnacle PCTV cards, the Twinhan DST cards,
-	  the pcHDTV HD2000 cards, the DViCO FusionHDTV Lite cards, and
-	  some AVerMedia cards.
-
-	  Since these cards have no MPEG decoder onboard, they transmit
-	  only compressed MPEG data over the PCI bus, so you need
-	  an external software decoder to watch TV on your computer.
-
-	  Say Y if you own such a device and want to use it.

-	  Since these cards have no MPEG decoder onboard, they transmit

- *
- *  In this case, without feed->pusi_seen you'll receive a garbage section

- *
- * Fix:
- * when demux is started, let feed->pusi_seen = 0 to
- * prevent initial feeding of garbage from the end of
- * previous section. When you for the first time see PUSI=1
- * then set feed->pusi_seen = 1

- * TODO:
- * - add smart card reader support for Conditional Access (CA)
- *
- * Card reader in Anysee is nothing more than ISO 7816 card reader.
- * There is no hardware CAM in any Anysee device sold.
- * In my understanding it should be implemented by making own module
- * for ISO 7816 card reader, like dvb_ca_en50221 is implemented. This
- * module registers serial interface that can be used to communicate
- * with any ISO 7816 smart card.
- *
- * Any help according to implement serial smart card reader support
- * is highly welcome!

+/*
+ * Programming the mspx4xx sound processor family
+ *
+ * (c) 1997-2001 Gerd Knorr <kraxel@bytesex.org>
+ *
+ * what works and what doesn't:
+ *
+ *  AM-Mono
+ *      Support for Hauppauge cards added (decoding handled by tuner) added by
+ *      Frederic Crozat <fcrozat@mail.dotcom.fr>
+ *
+ *  FM-Mono
+ *      should work. The stereo modes are backward compatible to FM-mono,
+ *      therefore FM-Mono should be allways available.
+ *
+ *  FM-Stereo (B/G, used in germany)
+ *      should work, with autodetect
+ *
+ *  FM-Stereo (satellite)
+ *      should work, no autodetect (i.e. default is mono, but you can
+ *      switch to stereo -- untested)
+ *
+ *  NICAM (B/G, L , used in UK, Scandinavia, Spain and France)
+ *      should work, with autodetect. Support for NICAM was added by
+ *      Pekka Pietikainen <pp@netppl.fi>
+ *
+ * TODO:
+ *   - better SAT support
+ *
+ * 980623  Thomas Sailer (sailer@ife.ee.ethz.ch)

+			 * The alternative to this understanding is

+			 * field first - the effect will be the two
+			 * buffers being returned in the wrong order,

+			 * by one field time (owing to the fifo nature
+			 * of videobuf).  Worse still, we'll be stuck
+			 * doing fields out of order now every time
+			 * until something else causes a field to be
+			 * dropped.  By effectively forcing a field to

+ *       I don't understand why many other drivers first allocate them with

+ *   Ben Capper:
+ *       On big-endian architectures (such as ppc) some extra steps
+ *       are needed. When reading and writing to the stat_com array
+ *       and fragment buffers, the device expects to see little-
+ *       endian values. The use of cpu_to_le32() and le32_to_cpu()
+ *       in this function (and one or two others in zoran_device.c)
+ *       ensure that these values are always stored in little-endian
+ *       form, regardless of architecture. The zr36057 does Very Bad

+ * CCDC hardware module for DM355
+ * ------------------------------
+ *
+ * This module is for configuring DM355 CCD controller of VPFE to capture
+ * Raw yuv or Bayer RGB data from a decoder. CCDC has several modules
+ * such as Defect Pixel Correction, Color Space Conversion etc to
+ * pre-process the Bayer RGB data, before writing it to SDRAM. This
+ * module also allows application to configure individual
+ * module parameters through VPFE_CMD_S_CCDC_RAW_PARAMS IOCTL.
+ * To do so, application include dm355_ccdc.h and vpfe_capture.h header
+ * files. The setparams() API is called by vpfe_capture driver
+ * to configure module parameters
+ *
+ * TODO: 1) Raw bayer parameter settings and bayer capture
+ * 	 2) Split module parameter structure to module specific ioctl structs
+ *	 3) add support for lense shading correction
+ *	 4) investigate if enum used for user space type definition
+ * 	    to be replaced by #defines or integer

+ * CCDC hardware module for DM6446
+ * ------------------------------
+ *
+ * This module is for configuring CCD controller of DM6446 VPFE to capture
+ * Raw yuv or Bayer RGB data from a decoder. CCDC has several modules
+ * such as Defect Pixel Correction, Color Space Conversion etc to
+ * pre-process the Raw Bayer RGB data, before writing it to SDRAM. This
+ * module also allows application to configure individual
+ * module parameters through VPFE_CMD_S_CCDC_RAW_PARAMS IOCTL.
+ * To do so, application includes dm644x_ccdc.h and vpfe_capture.h header
+ * files.  The setparams() API is called by vpfe_capture driver
+ * to configure module parameters. This file is named DM644x so that other
+ * variants such DM6443 may be supported using the same module.
+ *
+ * TODO: Test Raw bayer parameter settings and bayer capture
+ * 	 Split module parameter structure to module specific ioctl structs
+ * 	 investigate if enum used for user space type definition
+ * 	 to be replaced by #defines or integer
+ */

+ *
+ * Driver name : VPFE Capture driver
+ *    VPFE Capture driver allows applications to capture and stream video
+ *    frames on DaVinci SoCs (DM6446, DM355 etc) from a YUV source such as
+ *    TVP5146 or  Raw Bayer RGB image data from an image sensor
+ *    such as Microns' MT9T001, MT9T031 etc.
+ *
+ *    These SoCs have, in common, a Video Processing Subsystem (VPSS) that
+ *    consists of a Video Processing Front End (VPFE) for capturing
+ *    video/raw image data and Video Processing Back End (VPBE) for displaying
+ *    YUV data through an in-built analog encoder or Digital LCD port. This
+ *    driver is for capture through VPFE. A typical EVM using these SoCs have
+ *    following high level configuration.
+ *
+ *
+ *    decoder(TVP5146/		YUV/
+ * 	     MT9T001)   -->  Raw Bayer RGB ---> MUX -> VPFE (CCDC/ISIF)
+ *    				data input              |      |
+ *							V      |
+ *						      SDRAM    |
+ *							       V
+ *							   Image Processor
+ *							       |
+ *							       V
+ *							     SDRAM
+ *    The data flow happens from a decoder connected to the VPFE over a
+ *    YUV embedded (BT.656/BT.1120) or separate sync or raw bayer rgb interface
+ *    and to the input of VPFE through an optional MUX (if more inputs are
+ *    to be interfaced on the EVM). The input data is first passed through
+ *    CCDC (CCD Controller, a.k.a Image Sensor Interface, ISIF). The CCDC
+ *    does very little or no processing on YUV data and does pre-process Raw
+ *    Bayer RGB data through modules such as Defect Pixel Correction (DFC)
+ *    Color Space Conversion (CSC), data gain/offset etc. After this, data
+ *    can be written to SDRAM or can be connected to the image processing
+ *    block such as IPIPE (on DM355 only).
+ *
+ *    Features supported
+ *  		- MMAP IO
+ *		- Capture using TVP5146 over BT.656
+ *		- support for interfacing decoders using sub device model
+ *		- Work with DM355 or DM6446 CCDC to do Raw Bayer RGB/YUV
+ *		  data capture to SDRAM.
+ *    TODO list
+ *		- Support multiple REQBUF after open
+ *		- Support for de-allocating buffers through REQBUF
+ *		- Support for Raw Bayer RGB capture
+ *		- Support for chaining Image Processor
+ *		- Support for static allocation of buffers
+ *		- Support for USERPTR IO
+ *		- Support for STREAMON before QBUF
+ *		- Support for control ioctls

+ * @res: pointer to resizer private data structure
+ * @input: input frame size
+ * @output: output frame size
+ * @ratio : return calculated ratios
+ * return none
+ *
+ * The resizer uses a polyphase sample rate converter. The upsampling filter
+ * has a fixed number of phases that depend on the resizing ratio. As the ratio
+ * computation depends on the number of phases, we need to compute a first
+ * approximation and then refine it.
+ *
+ * The input/output/ratio relationship is given by the OMAP34xx TRM:
+ *
+ * - 8-phase, 4-tap mode (RSZ = 64 ~ 512)
+ *	iw = (32 * sph + (ow - 1) * hrsz + 16) >> 8 + 7
+ *	ih = (32 * spv + (oh - 1) * vrsz + 16) >> 8 + 4
+ * - 4-phase, 7-tap mode (RSZ = 513 ~ 1024)
+ *	iw = (64 * sph + (ow - 1) * hrsz + 32) >> 8 + 7
+ *	ih = (64 * spv + (oh - 1) * vrsz + 32) >> 8 + 7
+ *
+ * iw and ih are the input width and height after cropping. Those equations need
+ * to be satisfied exactly for the resizer to work correctly.
+ *
+ * The equations can't be easily reverted, as the >> 8 operation is not linear.
+ * In addition, not all input sizes can be achieved for a given output size. To
+ * get the highest input size lower than or equal to the requested input size,
+ * we need to compute the highest resizing ratio that satisfies the following
+ * inequality (taking the 4-tap mode width equation as an example)
+ *
+ *	iw >= (32 * sph + (ow - 1) * hrsz + 16) >> 8 - 7
+ *
+ * (where iw is the requested input width) which can be rewritten as
+ *
+ *	  iw - 7            >= (32 * sph + (ow - 1) * hrsz + 16) >> 8
+ *	 (iw - 7) << 8      >=  32 * sph + (ow - 1) * hrsz + 16 - b
+ *	((iw - 7) << 8) + b >=  32 * sph + (ow - 1) * hrsz + 16
+ *
+ * where b is the value of the 8 least significant bits of the right hand side
+ * expression of the last inequality. The highest resizing ratio value will be
+ * achieved when b is equal to its maximum value of 255. That resizing ratio
+ * value will still satisfy the original inequality, as b will disappear when
+ * the expression will be shifted right by 8.
+ *
+ * The reverted equations thus become
+ *
+ * - 8-phase, 4-tap mode
+ *	hrsz = ((iw - 7) * 256 + 255 - 16 - 32 * sph) / (ow - 1)
+ *	vrsz = ((ih - 4) * 256 + 255 - 16 - 32 * spv) / (oh - 1)
+ * - 4-phase, 7-tap mode
+ *	hrsz = ((iw - 7) * 256 + 255 - 32 - 64 * sph) / (ow - 1)
+ *	vrsz = ((ih - 7) * 256 + 255 - 32 - 64 * spv) / (oh - 1)
+ *
+ * The ratios are integer values, and are rounded down to ensure that the
+ * cropped input size is not bigger than the uncropped input size.
+ *
+ * As the number of phases/taps, used to select the correct equations to compute
+ * the ratio, depends on the ratio, we start with the 4-tap mode equations to
+ * compute an approximation of the ratio, and switch to the 7-tap mode equations
+ * if the approximation is higher than the ratio threshold.
+ *
+ * As the 7-tap mode equations will return a ratio smaller than or equal to the
+ * 4-tap mode equations, the resulting ratio could become lower than or equal to
+ * the ratio threshold. This 'equations loop' isn't an issue as long as the
+ * correct equations are used to compute the final input size. Starting with the
+ * 4-tap mode equations ensure that, in case of values resulting in a 'ratio
+ * loop', the smallest of the ratio values will be used, never exceeding the
+ * requested input size.
+ *
+ * We first clamp the output size according to the hardware capability to avoid
+ * auto-cropping the input more than required to satisfy the TRM equations. The
+ * minimum output size is achieved with a scaling factor of 1024. It is thus
+ * computed using the 7-tap equations.
+ *
+ *	min ow = ((iw - 7) * 256 - 32 - 64 * sph) / 1024 + 1
+ *	min oh = ((ih - 7) * 256 - 32 - 64 * spv) / 1024 + 1
+ *
+ * Similarly, the maximum output size is achieved with a scaling factor of 64
+ * and computed using the 4-tap equations.
+ *
+ *	max ow = ((iw - 7) * 256 + 255 - 16 - 32 * sph) / 64 + 1
+ *	max oh = ((ih - 4) * 256 + 255 - 16 - 32 * spv) / 64 + 1
+ *
+ * The additional +255 term compensates for the round down operation performed
+ * by the TRM equations when shifting the value right by 8 bits.
+ *
+ * We then compute and clamp the ratios (x1/4 ~ x4). Clamping the output size to
+ * the maximum value guarantees that the ratio value will never be smaller than
+ * the minimum, but it could still slightly exceed the maximum. Clamping the
+ * ratio will thus result in a resizing factor slightly larger than the
+ * requested value.
+ *
+ * To accommodate that, and make sure the TRM equations are satisfied exactly, we
+ * compute the input crop rectangle as the last step.
+ *
+ * As if the situation wasn't complex enough, the maximum output width depends
+ * on the vertical resizing ratio.  Fortunately, the output height doesn't
+ * depend on the horizontal resizing ratio. We can then start by computing the
+ * output height and the vertical ratio, and then move to computing the output
+ * width and the horizontal ratio.

+ * Stream management
+ *
+ * Every ISP pipeline has a single input and a single output. The input can be
+ * either a sensor or a video node. The output is always a video node.
+ *
+ * As every pipeline has an output video node, the ISP video objects at the
+ * pipeline output stores the pipeline state. It tracks the streaming state of
+ * both the input and output, as well as the availability of buffers.
+ *
+ * In sensor-to-memory mode, frames are always available at the pipeline input.
+ * Starting the sensor usually requires I2C transfers and must be done in
+ * interruptible context. The pipeline is started and stopped synchronously
+ * to the stream on/off commands. All modules in the pipeline will get their
+ * subdev set stream handler called. The module at the end of the pipeline must
+ * delay starting the hardware until buffers are available at its output.
+ *
+ * In memory-to-memory mode, starting/stopping the stream requires
+ * synchronization between the input and output. ISP modules can't be stopped
+ * in the middle of a frame, and at least some of the modules seem to become
+ * busy as soon as they're started, even if they don't receive a frame start
+ * event. For that reason frames need to be processed in single-shot mode. The
+ * driver needs to wait until a frame is completely processed and written to
+ * memory before restarting the pipeline for the next frame. Pipelined
+ * processing might be possible but requires more testing.
+ *
+ * Stream start must be delayed until buffers are available at both the input
+ * and output. The pipeline must be started in the videobuf queue callback with
+ * the buffers queue spinlock held. The modules subdev set stream operation must
+ * not sleep.

+    History of this driver (Steven Toth):
+      I was given a public release of a linux driver that included
+      support for the MaxLinear MXL5005S silicon tuner. Analysis of
+      the tuner driver showed clearly three things.
+
+      1. The tuner driver didn't support the LinuxTV tuner API
+	 so the code Realtek added had to be removed.
+
+      2. A significant amount of the driver is reference driver code
+	 from MaxLinear, I felt it was important to identify and
+	 preserve this.
+
+      3. New code has to be added to interface correctly with the
+	 LinuxTV API, as a regular kernel module.
+
+      Other than the reference driver enum's, I've clearly marked
+      sections of the code and retained the copyright of the
+      respective owners.

+   Basic firmware description. This will remain with

+
+   This represents an I2C firmware file encoded as a
+   string of unsigned char. Format is as follows:
+
+   char[0  ]=len0_MSB  -> len = len_MSB * 256 + len_LSB
+   char[1  ]=len0_LSB  -> length of first write transaction
+   char[2  ]=data0 -> first byte to be sent
+   char[3  ]=data1
+   char[4  ]=data2
+   char[   ]=...
+   char[M  ]=dataN  -> last byte to be sent
+   char[M+1]=len1_MSB  -> len = len_MSB * 256 + len_LSB
+   char[M+2]=len1_LSB  -> length of second write transaction
+   char[M+3]=data0
+   char[M+4]=data1
+   ...
+   etc.
+
+   The [len] value should be interpreted as follows:
+
+   len= len_MSB _ len_LSB
+   len=1111_1111_1111_1111   : End of I2C_SEQUENCE
+   len=0000_0000_0000_0000   : Reset command: Do hardware reset
+   len=0NNN_NNNN_NNNN_NNNN   : Normal transaction: number of bytes = {1:32767)
+   len=1WWW_WWWW_WWWW_WWWW   : Wait command: wait for {1:32767} ms
+
+   For the RESET and WAIT commands, the two following bytes will contain
+   immediately the length of the following transaction.

+ *
+ * Card reader in Anysee is nothing more than ISO 7816 card reader.
+ * There is no hardware CAM in any Anysee device sold.

+ * Some documentation about various registers as determined by trial and error.
+ *
+ * Register page 0:
+ *
+ * Address	Description
+ * 0x02		Red balance control
+ * 0x03		Green balance control
+ * 0x04 	Blue balance control
+ *		     Valus are inverted (0=max, 255=min).
+ *		     The Windows driver uses a quadratic approach to map
+ *		     the settable values (0-200) on register values:
+ *		     min=0x80, default=0x40, max=0x20
+ * 0x0f-0x20	Colors, saturation and exposure control
+ * 0xa2-0xab	Brightness, contrast and gamma control
+ * 0xb6		Sharpness control (bits 0-4)
+ *
+ * Register page 1:
+ *
+ * Address	Description
+ * 0x78		Global control, bit 6 controls the LED (inverted)
+ * 0x80		Compression balance, 2 interesting settings:
+ *		0x0f Default
+ *		0x50 Values >= this switch the camera to a lower compression,
+ *		     using the same table for both luminance and chrominance.
+ *		     This gives a sharper picture. Only usable when running
+ *		     at < 15 fps! Note currently the driver does not use this
+ *		     as the quality gain is small and the generated JPG-s are
+ *		     only understood by v4l-utils >= 0.8.9
+ *
+ * Register page 3:
+ *
+ * Address	Description
+ * 0x02		Clock divider 3-63, fps = 90 / val. Must be a multiple of 3 on
+ *		the 7302, so one of 3, 6, 9, ..., except when between 6 and 12?
+ * 0x03		Variable framerate ctrl reg2==3: 0 -> ~30 fps, 255 -> ~22fps
+ * 0x04		Another var framerate ctrl reg2==3, reg3==0: 0 -> ~30 fps,
+ *		63 -> ~27 fps, the 2 msb's must always be 1 !!
+ * 0x05		Another var framerate ctrl reg2==3, reg3==0, reg4==0xc0:
+ *		1 -> ~30 fps, 2 -> ~20 fps
+ * 0x0e		Exposure bits 0-7, 0-448, 0 = use full frame time
+ * 0x0f		Exposure bit 8, 0-448, 448 = no exposure at all
+ * 0x10		Gain 0-31
+ * 0x12		Another gain 0-31, unlike 0x10 this one seems to start with an
+ *		amplification value of 1 rather then 0 at its lowest setting
+ * 0x21		Bitfield: 0-1 unused, 2-3 vflip/hflip, 4-5 unknown, 6-7 unused
+ * 0x80		Another framerate control, best left at 1, moving it from 1 to
+ *		2 causes the framerate to become 3/4th of what it was, and
+ *		also seems to cause pixel averaging, resulting in an effective
+ *		resolution of 320x240 and thus a much blockier image
+ *
+ * The registers are accessed in the following functions:
+ *

+   This code forms the interface between the USB layers and the Philips
+   specific stuff. Some adanved stuff of the driver falls under an
+   NDA, signed between me and Philips B.V., Eindhoven, the Netherlands, and
+   is thus not distributed in source form. The binary pwcx.o module
+   contains the code that falls under the NDA.
+
+   In case you're wondering: 'pwc' stands for "Philips WebCam", but
+   I really didn't want to type 'philips_web_cam' every time (I'm lazy as
+   any Linux kernel hacker, but I don't like uncomprehensible abbreviations
+   without explanation).
+
+   Oh yes, convention: to disctinguish between all the various pointers to
+   device-structures, I use these names for the pointer variables:
+   udev: struct usb_device *
+   vdev: struct video_device (member of pwc_dev)
+   pdev: struct pwc_devive *

+ *
+ *   Copyright (C) 2007-2010 by Sensoray Company Inc.
+ *                              Dean Anderson
+ *
+ * Some video buffer code based on vivi driver:
+ *
+ * Sensoray 2255 device supports 4 simultaneous channels.
+ * The channels are not "crossbar" inputs, they are physically
+ * attached to separate video decoders.
+ *
+ * Because of USB2.0 bandwidth limitations. There is only a
+ * certain amount of data which may be transferred at one time.
+ *
+ * Example maximum bandwidth utilization:
+ *
+ * -full size, color mode YUYV or YUV422P: 2 channels at once
+ * -full or half size Grey scale: all 4 channels at once
+ * -half size, color mode YUYV or YUV422P: all 4 channels at once
+ * -full size, color mode YUYV or YUV422P 1/2 frame rate: all 4 channels
+ *  at once.

+ * SOF = ((SOF2 - SOF1) * PTS + SOF1 * STC2 - SOF2 * STC1) / (STC2 - STC1)   (1)

+ *
+ * TS = ((TS2 - TS1) * PTS + TS1 * SOF2 - TS2 * SOF1) / (SOF2 - SOF1)	     (2)
+ *
+ * SOF values are coded on 11 bits by USB. We extend their precision with 16
+ * decimal bits, leading to a 11.16 coding.
+ *
+ * TODO: To avoid surprises with device clock values, PTS/STC timestamps should
+ * be normalized using the nominal device clock frequency reported through the
+ * UVC descriptors.
+ *
+ * Both the PTS/STC and SOF counters roll over, after a fixed but device
+ * specific amount of time for PTS/STC and after 2048ms for SOF. As long as the
+ * sliding window size is smaller than the rollover period, differences computed
+ * on unsigned integers will produce the correct result. However, the p term in
+ * the linear relations will be miscomputed.
+ *
+ * To fix the issue, we subtract a constant from the PTS and STC values to bring
+ * PTS to half the 32 bit STC range. The sliding window STC values then fit into
+ * the 32 bit range without any rollover.
+ *
+ * Similarly, we add 2048 to the device SOF values to make sure that the SOF
+ * computed by (1) will never be smaller than 0. This offset is then compensated
+ * by adding 2048 to the SOF values used in (2). However, this doesn't prevent
+ * rollovers between (1) and (2): the SOF value computed by (1) can be slightly
+ * lower than 4096, and the host SOF counters can have rolled over to 2048. This
+ * case is handled by subtracting 2048 from the SOF value if it exceeds the host
+ * SOF value at the end of the sliding window.
+ *
+ * Finally we subtract a constant from the host timestamps to bring the first
+ * timestamp of the sliding window to 1s.

+/* Some general notes on the atomic requirements of VIDIOC_G/TRY/S_EXT_CTRLS:
+
+   It is not a fully atomic operation, just best-effort only. After all, if
+   multiple controls have to be set through multiple i2c writes (for example)
+   then some initial writes may succeed while others fail. Thus leaving the
+   system in an inconsistent state. The question is how much effort you are
+   willing to spend on trying to make something atomic that really isn't.
+
+   From the point of view of an application the main requirement is that
+   when you call VIDIOC_S_EXT_CTRLS and some values are invalid then an
+   error should be returned without actually affecting any controls.
+
+   If all the values are correct, then it is acceptable to just give up
+   in case of low-level errors.
+
+   It is important though that the application can tell when only a partial
+   configuration was done. The way we do that is through the error_idx field
+   of struct v4l2_ext_controls: if that is equal to the count field then no
+   controls were affected. Otherwise all controls before that index were
+   successful in performing their 'get' or 'set' operation, the control at
+   the given index failed, and you don't know what happened with the controls
+   after the failed one. Since if they were part of a control cluster they
+   could have been successfully processed (if a cluster member was encountered
+   at index < error_idx), they could have failed (if a cluster member was at
+   error_idx), or they may not have been processed yet (if the first cluster
+   member appeared after error_idx).
+
+   It is all fairly theoretical, though. In practice all you can do is to
+   bail out. If error_idx == count, then it is an application bug. If
+   error_idx < count then it is only an application bug if the error code was
+   EBUSY. That usually means that something started streaming just when you
+   tried to set the controls. In all other cases it is a driver/hardware
+   problem and all you can do is to retry or bail out.
+
+   Note that these rules do not apply to VIDIOC_TRY_EXT_CTRLS: since that
+   never modifies controls the error_idx is just set to whatever control
+   has an invalid value.

- * For sliced VBI output, we set up to use VIP-1.1, 8-bit mode,
- * NN counts 1 byte Dwords, an IDID with the VBI line # in it.
- * Thus, according to the VIP-2 Spec, our VBI ancillary data lines
- * (should!) look like:
- *	4 byte EAV code:          0xff 0x00 0x00 0xRP
- *	unknown number of possible idle bytes
- *	3 byte Anc data preamble: 0x00 0xff 0xff
- *	1 byte data identifier:   ne010iii (parity bits, 010, DID bits)
- *	1 byte secondary data id: nessssss (parity bits, SDID bits)
- *	1 byte data word count:   necccccc (parity bits, NN Dword count)
- *	2 byte Internal DID:	  VBI-line-# 0x80
- *	NN data bytes
- *	1 byte checksum
- *	Fill bytes needed to fil out to 4*NN bytes of payload
- *
- * The RP codes for EAVs when in VIP-1.1 mode, not in raw mode, &
- * in the vertical blanking interval are:
- *	0xb0 (Task         0 VerticalBlank HorizontalBlank 0 0 0 0)
- *	0xf0 (Task EvenField VerticalBlank HorizontalBlank 0 0 0 0)
- *
- * Since the V bit is only allowed to toggle in the EAV RP code, just
- * before the first active region line and for active lines, they are:
- *	0x90 (Task         0 0 HorizontalBlank 0 0 0 0)
- *	0xd0 (Task EvenField 0 HorizontalBlank 0 0 0 0)
- *
- * The user application DID bytes we care about are:
- *	0x91 (1 0 010        0 !ActiveLine AncDataPresent)
- *	0x55 (0 1 010 2ndField !ActiveLine AncDataPresent)

-	 *
-	 * an error of less than 0.13 ppm which is way, way better than any off

- * CCDC hardware module for DM355
- * ------------------------------
- *
- * This module is for configuring DM355 CCD controller of VPFE to capture
- * Raw yuv or Bayer RGB data from a decoder. CCDC has several modules
- * such as Defect Pixel Correction, Color Space Conversion etc to
- * pre-process the Bayer RGB data, before writing it to SDRAM. This
- * module also allows application to configure individual
- * module parameters through VPFE_CMD_S_CCDC_RAW_PARAMS IOCTL.
- * To do so, application include dm355_ccdc.h and vpfe_capture.h header
- * files. The setparams() API is called by vpfe_capture driver
- * to configure module parameters
- *
- * TODO: 1) Raw bayer parameter settings and bayer capture
- * 	 2) Split module parameter structure to module specific ioctl structs
- *	 3) add support for lense shading correction
- *	 4) investigate if enum used for user space type definition
- * 	    to be replaced by #defines or integer

- * CCDC hardware module for DM6446
- * ------------------------------
- *
- * This module is for configuring CCD controller of DM6446 VPFE to capture
- * Raw yuv or Bayer RGB data from a decoder. CCDC has several modules
- * such as Defect Pixel Correction, Color Space Conversion etc to
- * pre-process the Raw Bayer RGB data, before writing it to SDRAM. This
- * module also allows application to configure individual
- * module parameters through VPFE_CMD_S_CCDC_RAW_PARAMS IOCTL.
- * To do so, application includes dm644x_ccdc.h and vpfe_capture.h header
- * files.  The setparams() API is called by vpfe_capture driver
- * to configure module parameters. This file is named DM644x so that other
- * variants such DM6443 may be supported using the same module.
- *
- * TODO: Test Raw bayer parameter settings and bayer capture
- * 	 Split module parameter structure to module specific ioctl structs
- * 	 investigate if enum used for user space type definition
- * 	 to be replaced by #defines or integer
- */

- *
- * Driver name : VPFE Capture driver
- *    VPFE Capture driver allows applications to capture and stream video
- *    frames on DaVinci SoCs (DM6446, DM355 etc) from a YUV source such as
- *    TVP5146 or  Raw Bayer RGB image data from an image sensor
- *    such as Microns' MT9T001, MT9T031 etc.
- *
- *    These SoCs have, in common, a Video Processing Subsystem (VPSS) that
- *    consists of a Video Processing Front End (VPFE) for capturing
- *    video/raw image data and Video Processing Back End (VPBE) for displaying
- *    YUV data through an in-built analog encoder or Digital LCD port. This
- *    driver is for capture through VPFE. A typical EVM using these SoCs have
- *    following high level configuration.
- *
- *
- *    decoder(TVP5146/		YUV/
- * 	     MT9T001)   -->  Raw Bayer RGB ---> MUX -> VPFE (CCDC/ISIF)
- *    				data input              |      |
- *							V      |
- *						      SDRAM    |
- *							       V
- *							   Image Processor
- *							       |
- *							       V
- *							     SDRAM
- *    The data flow happens from a decoder connected to the VPFE over a
- *    YUV embedded (BT.656/BT.1120) or separate sync or raw bayer rgb interface
- *    and to the input of VPFE through an optional MUX (if more inputs are
- *    to be interfaced on the EVM). The input data is first passed through
- *    CCDC (CCD Controller, a.k.a Image Sensor Interface, ISIF). The CCDC
- *    does very little or no processing on YUV data and does pre-process Raw
- *    Bayer RGB data through modules such as Defect Pixel Correction (DFC)
- *    Color Space Conversion (CSC), data gain/offset etc. After this, data
- *    can be written to SDRAM or can be connected to the image processing
- *    block such as IPIPE (on DM355 only).
- *
- *    Features supported
- *  		- MMAP IO
- *		- Capture using TVP5146 over BT.656
- *		- support for interfacing decoders using sub device model
- *		- Work with DM355 or DM6446 CCDC to do Raw Bayer RGB/YUV
- *		  data capture to SDRAM.
- *    TODO list
- *		- Support multiple REQBUF after open

- * The FX2 chip does not give us a zero length read at end of frame.
- * It does, however, give a short read at the end of a frame, if
- * necessary, rather than run two frames together.
- *
- * By choosing the right bulk transfer size, we are guaranteed to always
- * get a short read for the last read of each frame.  Frame sizes are
- * always a composite number (width * height, or a multiple) so if we
- * choose a prime number, we are guaranteed that the last read of a
- * frame will be short.
- *
- * But it isn't that easy: the 2.6 kernel requires a multiple of 4KB,
- * otherwise EOVERFLOW "babbling" errors occur.  I have not been able
- * to figure out why.  [PMiller]
- *
- * The constant (13 * 4096) is the largest "prime enough" number less than 64KB.
- *
- * It isn't enough to know the number of bytes per frame, in case we
- * have data dropouts or buffer overruns (even though the FX2 double
- * buffers, there are some pretty strict real time constraints for
- * isochronous transfer for larger frame sizes).

- * Some documentation about various registers as determined by trial and error.
- *
- * Register page 1:
- *
- * Address	Description
- * 0x78		Global control, bit 6 controls the LED (inverted)
- * 0x80		Compression balance, 2 interesting settings:
- *		0x0f Default
- *		0x50 Values >= this switch the camera to a lower compression,
- *		     using the same table for both luminance and chrominance.
- *		     This gives a sharper picture. Only usable when running
- *		     at < 15 fps! Note currently the driver does not use this
- *		     as the quality gain is small and the generated JPG-s are
- *		     only understood by v4l-utils >= 0.8.9
- *
- * Register page 3:
- *
- * Address	Description
- * 0x02		Clock divider 3-63, fps = 90 / val. Must be a multiple of 3 on
- *		the 7302, so one of 3, 6, 9, ..., except when between 6 and 12?
- * 0x03		Variable framerate ctrl reg2==3: 0 -> ~30 fps, 255 -> ~22fps
- * 0x04		Another var framerate ctrl reg2==3, reg3==0: 0 -> ~30 fps,
- *		63 -> ~27 fps, the 2 msb's must always be 1 !!
- * 0x05		Another var framerate ctrl reg2==3, reg3==0, reg4==0xc0:
- *		1 -> ~30 fps, 2 -> ~20 fps
- * 0x0e		Exposure bits 0-7, 0-448, 0 = use full frame time
- * 0x0f		Exposure bit 8, 0-448, 448 = no exposure at all
- * 0x10		Gain 0-31
- * 0x12		Another gain 0-31, unlike 0x10 this one seems to start with an
- *		amplification value of 1 rather then 0 at its lowest setting
- * 0x21		Bitfield: 0-1 unused, 2-3 vflip/hflip, 4-5 unknown, 6-7 unused
- * 0x80		Another framerate control, best left at 1, moving it from 1 to
- *		2 causes the framerate to become 3/4th of what it was, and
- *		also seems to cause pixel averaging, resulting in an effective
- *		resolution of 320x240 and thus a much blockier image
- *
- * The registers are accessed in the following functions:
- *
- * Page | Register   | Function
- * -----+------------+---------------------------------------------------
- *  0   | 0x0f..0x20 | setcolors()
- *  0   | 0xa2..0xab | setbrightcont()
- *  0   | 0xc5       | setredbalance()
- *  0   | 0xc6       | setwhitebalance()
- *  0   | 0xc7       | setbluebalance()
- *  0   | 0xdc       | setbrightcont(), setcolors()
- *  3   | 0x02       | setexposure()
- *  3   | 0x10, 0x12 | setgain()
- *  3   | 0x11       | setcolors(), setgain(), setexposure(), sethvflip()
- *  3   | 0x21       | sethvflip()

- *
- * During I2C reads, the KS0127 only samples for a stop condition
- * during the place where the acknowledge bit should be. Any standard
- * I2C implementation (correctly) throws in another clock transition
- * at the 9th bit, and the KS0127 will not recognize the stop condition
- * and will continue to clock out data.

- * Programming the mspx4xx sound processor family
- *
- * (c) 1997-2001 Gerd Knorr <kraxel@bytesex.org>
- *
- * what works and what doesn't:
- *
- *  AM-Mono
- *      Support for Hauppauge cards added (decoding handled by tuner) added by
- *      Frederic Crozat <fcrozat@mail.dotcom.fr>
- *
- *  FM-Mono
- *      should work. The stereo modes are backward compatible to FM-mono,
- *      therefore FM-Mono should be allways available.
- *
- *  FM-Stereo (B/G, used in germany)
- *      should work, with autodetect
- *
- *  FM-Stereo (satellite)
- *      should work, no autodetect (i.e. default is mono, but you can
- *      switch to stereo -- untested)
- *
- *  NICAM (B/G, L , used in UK, Scandinavia, Spain and France)
- *      should work, with autodetect. Support for NICAM was added by
- *      Pekka Pietikainen <pp@netppl.fi>
- *
- * TODO:
- *   - better SAT support
- *
- * 980623  Thomas Sailer (sailer@ife.ee.ethz.ch)
- *         using soundcore instead of OSS

- * @ratio : return calculated ratios
- * return none
- *
- * The resizer uses a polyphase sample rate converter. The upsampling filter
- * has a fixed number of phases that depend on the resizing ratio. As the ratio
- * computation depends on the number of phases, we need to compute a first
- * approximation and then refine it.
- *
- * The input/output/ratio relationship is given by the OMAP34xx TRM:
- *
- * - 8-phase, 4-tap mode (RSZ = 64 ~ 512)
- *	iw = (32 * sph + (ow - 1) * hrsz + 16) >> 8 + 7
- *	ih = (32 * spv + (oh - 1) * vrsz + 16) >> 8 + 4
- * - 4-phase, 7-tap mode (RSZ = 513 ~ 1024)
- *	iw = (64 * sph + (ow - 1) * hrsz + 32) >> 8 + 7
- *	ih = (64 * spv + (oh - 1) * vrsz + 32) >> 8 + 7
- *
- * iw and ih are the input width and height after cropping. Those equations need
- * to be satisfied exactly for the resizer to work correctly.
- *
- * The equations can't be easily reverted, as the >> 8 operation is not linear.
- * In addition, not all input sizes can be achieved for a given output size. To
- * get the highest input size lower than or equal to the requested input size,
- * we need to compute the highest resizing ratio that satisfies the following
- * inequality (taking the 4-tap mode width equation as an example)
- *
- *	iw >= (32 * sph + (ow - 1) * hrsz + 16) >> 8 - 7
- *
- * (where iw is the requested input width) which can be rewritten as
- *
- *	  iw - 7            >= (32 * sph + (ow - 1) * hrsz + 16) >> 8
- *	 (iw - 7) << 8      >=  32 * sph + (ow - 1) * hrsz + 16 - b
- *	((iw - 7) << 8) + b >=  32 * sph + (ow - 1) * hrsz + 16
- *
- * where b is the value of the 8 least significant bits of the right hand side
- * expression of the last inequality. The highest resizing ratio value will be
- * achieved when b is equal to its maximum value of 255. That resizing ratio
- * value will still satisfy the original inequality, as b will disappear when
- * the expression will be shifted right by 8.
- *
- * The reverted the equations thus become
- *
- * - 8-phase, 4-tap mode
- *	hrsz = ((iw - 7) * 256 + 255 - 16 - 32 * sph) / (ow - 1)
- *	vrsz = ((ih - 4) * 256 + 255 - 16 - 32 * spv) / (oh - 1)
- * - 4-phase, 7-tap mode
- *	hrsz = ((iw - 7) * 256 + 255 - 32 - 64 * sph) / (ow - 1)
- *	vrsz = ((ih - 7) * 256 + 255 - 32 - 64 * spv) / (oh - 1)
- *
- * The ratios are integer values, and are rounded down to ensure that the
- * cropped input size is not bigger than the uncropped input size.
- *
- * As the number of phases/taps, used to select the correct equations to compute
- * the ratio, depends on the ratio, we start with the 4-tap mode equations to
- * compute an approximation of the ratio, and switch to the 7-tap mode equations
- * if the approximation is higher than the ratio threshold.
- *
- * As the 7-tap mode equations will return a ratio smaller than or equal to the
- * 4-tap mode equations, the resulting ratio could become lower than or equal to
- * the ratio threshold. This 'equations loop' isn't an issue as long as the
- * correct equations are used to compute the final input size. Starting with the
- * 4-tap mode equations ensure that, in case of values resulting in a 'ratio
- * loop', the smallest of the ratio values will be used, never exceeding the
- * requested input size.
- *
- * We first clamp the output size according to the hardware capabilitie to avoid
- * auto-cropping the input more than required to satisfy the TRM equations. The
- * minimum output size is achieved with a scaling factor of 1024. It is thus
- * computed using the 7-tap equations.
- *
- *	min ow = ((iw - 7) * 256 - 32 - 64 * sph) / 1024 + 1
- *	min oh = ((ih - 7) * 256 - 32 - 64 * spv) / 1024 + 1
- *
- * Similarly, the maximum output size is achieved with a scaling factor of 64
- * and computed using the 4-tap equations.
- *
- *	max ow = ((iw - 7) * 256 + 255 - 16 - 32 * sph) / 64 + 1
- *	max oh = ((ih - 4) * 256 + 255 - 16 - 32 * spv) / 64 + 1
- *
- * The additional +255 term compensates for the round down operation performed
- * by the TRM equations when shifting the value right by 8 bits.
- *
- * We then compute and clamp the ratios (x1/4 ~ x4). Clamping the output size to
- * the maximum value guarantees that the ratio value will never be smaller than
- * the minimum, but it could still slightly exceed the maximum. Clamping the
- * ratio will thus result in a resizing factor slightly larger than the
- * requested value.
- *
- * To accommodate that, and make sure the TRM equations are satisfied exactly, we
- * compute the input crop rectangle as the last step.
- *
- * As if the situation wasn't complex enough, the maximum output width depends
- * on the vertical resizing ratio.  Fortunately, the output height doesn't
- * depend on the horizontal resizing ratio. We can then start by computing the
- * output height and the vertical ratio, and then move to computing the output
- * width and the horizontal ratio.

- * Stream management
- *
- * Every ISP pipeline has a single input and a single output. The input can be
- * either a sensor or a video node. The output is always a video node.
- *
- * As every pipeline has an output video node, the ISP video objects at the
- * pipeline output stores the pipeline state. It tracks the streaming state of
- * both the input and output, as well as the availability of buffers.
- *
- * In sensor-to-memory mode, frames are always available at the pipeline input.
- * Starting the sensor usually requires I2C transfers and must be done in
- * interruptible context. The pipeline is started and stopped synchronously
- * to the stream on/off commands. All modules in the pipeline will get their
- * subdev set stream handler called. The module at the end of the pipeline must
- * delay starting the hardware until buffers are available at its output.
- *
- * In memory-to-memory mode, starting/stopping the stream requires
- * synchronization between the input and output. ISP modules can't be stopped
- * in the middle of a frame, and at least some of the modules seem to become
- * busy as soon as they're started, even if they don't receive a frame start
- * event. For that reason frames need to be processed in single-shot mode. The
- * driver needs to wait until a frame is completely processed and written to
- * memory before restarting the pipeline for the next frame. Pipelined
- * processing might be possible but requires more testing.
- *
- * Stream start must be delayed until buffers are available at both the input
- * and output. The pipeline must be started in the videobuf queue callback with
- * the buffers queue spinlock held. The modules subdev set stream operation must
- * not sleep.

-	---help---
-	  This option enables the operation of a sysfs based
-	  interface for query and control of the pvrusb2 driver.
-
-	  This is not generally needed for v4l applications,
-	  although certain applications are optimized to take
-	  advantage of this feature.
-
-	  If you are in doubt, say Y.
-
-	  Note: This feature is experimental and subject to change.

- * Some video buffer code based on vivi driver:
- *
- * Sensoray 2255 device supports 4 simultaneous channels.
- * The channels are not "crossbar" inputs, they are physically
- * attached to separate video decoders.
- *
- * Because of USB2.0 bandwidth limitations. There is only a
- * certain amount of data which may be transferred at one time.
- *
- * Example maximum bandwidth utilization:
- *
- * -full size, color mode YUYV or YUV422P: 2 channels at once
- * -full or half size Grey scale: all 4 channels at once
- * -half size, color mode YUYV or YUV422P: all 4 channels at once
- * -full size, color mode YUYV or YUV422P 1/2 frame rate: all 4 channels
- *  at once.

-	 *
-	 * tFlash_strobe_width_ctrl E N, [1 - 0xffff]
-	 * flash_strobe_adjustment E N, [1 - 0xff]
-	 *
-	 * The formula above is written as below to keep it on one
-	 * line:
-	 *
-	 * l / 10^6 = w / e * a
-	 *
-	 * Let's mark w * a by x:
-	 *
-	 * x = w * a
-	 *
-	 * Thus, we get:
-	 *
-	 * x = l * e / 10^6
-	 *
-	 * The strobe width must be at least as long as requested,
-	 * thus rounding upwards is needed.
-	 *
-	 * x = (l * e + 10^6 - 1) / 10^6
-	 * -----------------------------
-	 *
-	 * Maximum possible accuracy is wanted at all times. Thus keep
-	 * a as small as possible.
-	 *
-	 * Calculate a, assuming maximum w, with rounding upwards:
-	 *
-	 * a = (x + (2^16 - 1) - 1) / (2^16 - 1)
-	 * -------------------------------------
-	 *
-	 * Thus, we also get w, with that a, with rounding upwards:
-	 *
-	 * w = (x + a - 1) / a
-	 * -------------------
-	 *
-	 * To get limits:
-	 *
-	 * x E [1, (2^16 - 1) * (2^8 - 1)]
-	 *
-	 * Substituting maximum x to the original formula (with rounding),
-	 * the maximum l is thus
-	 *
-	 * (2^16 - 1) * (2^8 - 1) * 10^6 = l * e + 10^6 - 1
-	 *
-	 * l = (10^6 * (2^16 - 1) * (2^8 - 1) - 10^6 + 1) / e

-	 * flash_strobe_length must be clamped between 1 and

- *
- * This driver is written by Jose Ignacio Gijon and Joerg Heckenbach.
- * It was based on USB CPiA driver written by Peter Pregler,
- * Scott J. Bertin and Johannes Erdfelt
- * Ideas are taken from bttv driver by Ralph Metzler, Marcus Metzler &
- * Gerd Knorr and zoran 36120/36125 driver by Pauline Middelink
- * Updates to driver completed by Dwaine P. Garden
- *
- *
- * TODO:
- *     - use submit_urb for all setup packets
- *     - Fix memory settings for nt1004. It is 4 times as big as the
- *       nt1003 memory.
- *     - Add audio on endpoint 3 for nt1004 chip.
- *         Seems impossible, needs a codec interface.  Which one?
- *     - Clean up the driver.
- *     - optimization for performance.
- *     - Add Videotext capability (VBI).  Working on it.....
- *     - Check audio for other devices

- * uvc_video_clock_update - Update the buffer timestamp
- *
- * This function converts the buffer PTS timestamp to the host clock domain by
- * going through the USB SOF clock domain and stores the result in the V4L2
- * buffer timestamp field.
- *
- * The relationship between the device clock and the host clock isn't known.
- * However, the device and the host share the common USB SOF clock which can be
- * used to recover that relationship.
- *
- * The relationship between the device clock and the USB SOF clock is considered
- * to be linear over the clock samples sliding window and is given by
- *
- * SOF = m * PTS + p
- *
- * Several methods to compute the slope (m) and intercept (p) can be used. As
- * the clock drift should be small compared to the sliding window size, we
- * assume that the line that goes through the points at both ends of the window
- * is a good approximation. Naming those points P1 and P2, we get
- *
- * SOF = (SOF2 - SOF1) / (STC2 - STC1) * PTS
- *     + (SOF1 * STC2 - SOF2 * STC1) / (STC2 - STC1)
- *
- * or
- *
- * SOF = ((SOF2 - SOF1) * PTS + SOF1 * STC2 - SOF2 * STC1) / (STC2 - STC1)   (1)
- *
- * to avoid loosing precision in the division. Similarly, the host timestamp is
- * computed with
- *
- * TS = ((TS2 - TS1) * PTS + TS1 * SOF2 - TS2 * SOF1) / (SOF2 - SOF1)	     (2)
- *
- * SOF values are coded on 11 bits by USB. We extend their precision with 16
- * decimal bits, leading to a 11.16 coding.
- *
- * TODO: To avoid surprises with device clock values, PTS/STC timestamps should
- * be normalized using the nominal device clock frequency reported through the
- * UVC descriptors.
- *
- * Both the PTS/STC and SOF counters roll over, after a fixed but device
- * specific amount of time for PTS/STC and after 2048ms for SOF. As long as the
- * sliding window size is smaller than the rollover period, differences computed
- * on unsigned integers will produce the correct result. However, the p term in
- * the linear relations will be miscomputed.
- *
- * To fix the issue, we subtract a constant from the PTS and STC values to bring
- * PTS to half the 32 bit STC range. The sliding window STC values then fit into
- * the 32 bit range without any rollover.
- *
- * Similarly, we add 2048 to the device SOF values to make sure that the SOF
- * computed by (1) will never be smaller than 0. This offset is then compensated
- * by adding 2048 to the SOF values used in (2). However, this doesn't prevent
- * rollovers between (1) and (2): the SOF value computed by (1) can be slightly
- * lower than 4096, and the host SOF counters can have rolled over to 2048. This
- * case is handled by subtracting 2048 from the SOF value if it exceeds the host
- * SOF value at the end of the sliding window.
- *
- * Finally we subtract a constant from the host timestamps to bring the first
- * timestamp of the sliding window to 1s.

-/* Some general notes on the atomic requirements of VIDIOC_G/TRY/S_EXT_CTRLS:
-
-   It is not a fully atomic operation, just best-effort only. After all, if
-   multiple controls have to be set through multiple i2c writes (for example)
-   then some initial writes may succeed while others fail. Thus leaving the
-   system in an inconsistent state. The question is how much effort you are
-   willing to spend on trying to make something atomic that really isn't.
-
-   From the point of view of an application the main requirement is that
-   when you call VIDIOC_S_EXT_CTRLS and some values are invalid then an
-   error should be returned without actually affecting any controls.
-
-   If all the values are correct, then it is acceptable to just give up
-   in case of low-level errors.
-
-   It is important though that the application can tell when only a partial
-   configuration was done. The way we do that is through the error_idx field
-   of struct v4l2_ext_controls: if that is equal to the count field then no
-   controls were affected. Otherwise all controls before that index were
-   successful in performing their 'get' or 'set' operation, the control at
-   the given index failed, and you don't know what happened with the controls
-   after the failed one. Since if they were part of a control cluster they
-   could have been successfully processed (if a cluster member was encountered
-   at index < error_idx), they could have failed (if a cluster member was at
-   error_idx), or they may not have been processed yet (if the first cluster
-   member appeared after error_idx).
-
-   It is all fairly theoretical, though. In practice all you can do is to
-   bail out. If error_idx == count, then it is an application bug. If
-   error_idx < count then it is only an application bug if the error code was
-   EBUSY. That usually means that something started streaming just when you
-   tried to set the controls. In all other cases it is a driver/hardware
-   problem and all you can do is to retry or bail out.
-
-   Note that these rules do not apply to VIDIOC_TRY_EXT_CTRLS: since that
-   never modifies controls the error_idx is just set to whatever control
-   has an invalid value.

- *   Allocate the MJPEG grab buffers.

- *   (RJ: This statement is from Dave Perks' original driver,
- *   I could never check it because I have a zr36067)
- *
- *   RJ: The contents grab buffers needs never be accessed in the driver.
- *       Therefore there is no need to allocate them with vmalloc in order
- *       to get a contiguous virtual memory space.
- *       I don't understand why many other drivers first allocate them with

- *       virtual addresses) and then again have to make a lot of efforts

- *
- *   Ben Capper:
- *       On big-endian architectures (such as ppc) some extra steps
- *       are needed. When reading and writing to the stat_com array
- *       and fragment buffers, the device expects to see little-
- *       endian values. The use of cpu_to_le32() and le32_to_cpu()
- *       in this function (and one or two others in zoran_device.c)
- *       ensure that these values are always stored in little-endian
- *       form, regardless of architecture. The zr36057 does Very Bad
- *       Things on big endian architectures if the stat_com array

+	   Important: this feature is experimental so far and the on-flash

+
+	   Fastmap is a mechanism which allows attaching an UBI device
+	   in nearly constant time. Instead of scanning the whole MTD device it
+	   only has to locate a checkpoint (called fastmap) on the device.
+	   The on-flash fastmap contains all information needed to attach
+	   the device. Using fastmap makes only sense on large devices where
+	   attaching by scanning takes long. UBI will not automatically install
+	   a fastmap on old images, but you can set the UBI module parameter
+	   fm_autoconvert to 1 if you want so. Please note that fastmap-enabled
+	   images are still usable with UBI implementations without
+	   fastmap support. On typical flash devices the whole fastmap fits
+	   into one PEB. UBI will reserve PEBs to hold two fastmaps.
+
+	   If in doubt, say "N".

+ * This file supports the three variants of Armada XP SoCs that are
+ * available: mv78230, mv78260 and mv78460. From a pin muxing
+ * perspective, the mv78230 has 49 MPP pins. The mv78260 and mv78460
+ * both have 67 MPP pins (more GPIOs and address lines for the memory
+ * bus mainly). The only difference between the mv78260 and the
+ * mv78460 in terms of pin muxing is the addition of two functions on
+ * pins 43 and 56 to access the VDD of the CPU2 and 3 (mv78260 has two
+ * cores, mv78460 has four cores).

-
-SUPPORTED HARDWARE
-------------------
-
-This driver is intended for use with hardware having USB ID 05e1:0408.
-Two kinds of EasyCAP have this USB ID, namely:
-
-    *  EasyCAP USB 2.0 Video Adapter with Audio, Model DC60,
-       having input cables labelled CVBS, S-VIDEO, AUDIO(L), AUDIO(R)
-
-    *  EasyCAP002 4-Channel USB 2.0 DVR, having input cables labelled
-       1, 2, 3, 4 and an unlabelled input cable for a microphone.
-
-
-BUILD OPTIONS AND DEPENDENCIES
-------------------------------
-
-Unless EASYCAP_DEBUG is defined during compilation it will not be possible
-to select a debug level at the time of module installation.
-
-
-KNOWN RUNTIME ISSUES
---------------------
-
-(1) Intentionally, this driver will not stream material which is unambiguously
-identified by the hardware as copy-protected.  Normal video output will be
-present for about a minute but will then freeze when this situation arises.
-
-(2) The controls for luminance, contrast, saturation, hue and volume may not
-always work properly.
-
-(3) Reduced-resolution S-Video seems to suffer from moire artefacts.
-
-
-INPUT NUMBERING
----------------
-
-For the EasyCAP with S-VIDEO input cable the driver regards a request for
-inputs numbered 0 or 1 as referring to CVBS and a request for input
-numbered 5 as referring to S-VIDEO.
-
-For the EasyCAP with four CVBS inputs the driver expects to be asked for
-any one of inputs numbered 1,2,3,4.  If input 0 is asked for, it is
-interpreted as input 1.
-
-
-MODULE PARAMETERS
------------------
-
-Three module parameters are defined:
-
-debug      the easycap module is configured at diagnostic level n (0 to 9)
-gain       audio gain level n (0 to 31, default is 16)
-bars       whether to display testcard bars when incoming video signal is lost
-           0 => no, 1 => yes (default)
-
-
-SUPPORTED TV STANDARDS AND RESOLUTIONS
---------------------------------------
-
-The following TV standards are natively supported by the hardware and are
-usable as (for example) the "norm=" parameter in the mplayer command:
-
-    PAL_BGHIN,    NTSC_N_443,
-    PAL_Nc,       NTSC_N,
-    SECAM,        NTSC_M,        NTSC_M_JP,
-    PAL_60,       NTSC_443,
-    PAL_M.
-
-In addition, the driver offers "custom" pseudo-standards with a framerate
-which is 20% of the usual framerate.  These pseudo-standards are named:
-
-    PAL_BGHIN_SLOW,    NTSC_N_443_SLOW,
-    PAL_Nc_SLOW,       NTSC_N_SLOW,
-    SECAM_SLOW,        NTSC_M_SLOW,        NTSC_M_JP_SLOW,
-    PAL_60_SLOW,       NTSC_443_SLOW,
-    PAL_M_SLOW.
-
-
-The available picture sizes are:
-
-     at 25 frames per second:   720x576, 704x576, 640x480, 360x288, 320x240;
-     at 30 frames per second:   720x480, 640x480, 360x240, 320x240.
-
-
-WHAT'S TESTED AND WHAT'S NOT
-----------------------------
-
-This driver is known to work with mplayer, mencoder, tvtime, zoneminder,
-xawtv, gstreamer and sufficiently recent versions of vlc.  An interface
-to ffmpeg is implemented, but serious audio-video synchronization problems
-remain.
-
-The driver is designed to support all the TV standards accepted by the
-hardware, but as yet it has actually been tested on only a few of these.
-
-I have been unable to test and calibrate the S-video input myself because I
-do not possess any equipment with S-video output.
-
-
-UDEV RULES
-----------
-
-In order that the special files /dev/easycap0 and /dev/easysnd1 are created
-with conveniently relaxed permissions when the EasyCAP is plugged in, a file
-is preferably to be provided in directory /etc/udev/rules.d with content:
-
-ACTION!="add|change", GOTO="easycap_rules_end"
-ATTRS{idVendor}=="05e1", ATTRS{idProduct}=="0408", \
-	MODE="0666", OWNER="root", GROUP="root"
-LABEL="easycap_rules_end"
-
-
-MODPROBE CONFIGURATION
-----------------------
-
-The easycap module is in competition with the module snd-usb-audio for the
-EasyCAP's audio channel, and its installation can be aided by providing a
-file in directory /etc/modprobe.d with content:
-
-options easycap  gain=16 bars=1
-install easycap /sbin/rmmod snd-usb-audio; /sbin/modprobe --ignore-install easycap
-
-
-ACKNOWLEGEMENTS AND REFERENCES
-------------------------------
-This driver makes use of information contained in the Syntek Semicon DC-1125
-Driver, presently maintained at http://sourceforge.net/projects/syntekdriver/
-by Nicolas Vivien.  Particularly useful has been a patch to the latter driver
-provided by Ivor Hewitt in January 2009.  The NTSC implementation is taken
-from the work of Ben Trask.

- *  THIS ROUTINE REQUIRES THAT ALL THE DATA TO BE READ RESIDES ON ONE PAGE
- *  AND THAT ALL THE DATA TO BE WRITTEN RESIDES ON ONE (DIFFERENT) PAGE.
- *  THE CALLING ROUTINE MUST ENSURE THAT THIS REQUIREMENT IS MET, AND MUST
- *  ALSO ENSURE THAT much IS EVEN.
- *
- *  much BYTES ARE READ, AT LEAST (bytesperpixel * much)/2 BYTES ARE WRITTEN
- *  IF THERE IS NO DECIMATION, HALF THIS AMOUNT IF THERE IS DECIMATION.
- *
- *  mask IS ZERO WHEN NO SPECIAL BEHAVIOUR REQUIRED. OTHERWISE IT IS SET THUS:
- *     0x03 & mask =  number of bytes to be written to cache instead of to
- *                    frame buffer
- *     0x04 & mask => use argument margin to set the chrominance for last pixel
- *     0x08 & mask => do not set the chrominance for last pixel
- *
- *  YUV to RGB CONVERSION IS (OR SHOULD BE) ITU-R BT 601.
- *
- *  THERE IS A LOT OF CODE REPETITION IN THIS ROUTINE IN ORDER TO AVOID
- *  INEFFICIENT SWITCHING INSIDE INNER LOOPS.  REARRANGING THE LOGIC TO
- *  REDUCE CODE LENGTH WILL GENERALLY IMPAIR RUNTIME PERFORMANCE.  BEWARE.
