+Debug Control and Status Register (DCSR) Binding
+Copyright 2011 Freescale Semiconductor Inc.
+
+NOTE: The bindings described in this document are preliminary and subject
+to change.  Some of the compatible strings that contain only generic names
+may turn out to be inappropriate, or need additional properties to describe
+the integration of the block with the rest of the chip.

+=====================================================================
+Debug Control and Status Register Memory Map
+
+Description
+
+This node defines the base address and range for the
+defined DCSR Memory Map. Child nodes will describe the individual
+debug blocks defined within this memory space.
+
+PROPERTIES
+
+	- compatible
+	Usage: required
+	Value type: <string>
+	Definition: Must include "fsl,dcsr" and "simple-bus".
+	The DCSR space exists in the memory-mapped bus.
+
+	- #address-cells
+	Usage: required
+	Value type: <u32>
+	Definition: A standard property.  Defines the number of cells
+	or representing physical addresses in child nodes.
+
+	- #size-cells
+	Usage: required
+	Value type: <u32>
+	Definition: A standard property.  Defines the number of cells
+	or representing the size of physical addresses in
+	child nodes.
+
+	- ranges
+	Usage: required
+	Value type: <prop-encoded-array>
+	Definition: A standard property. Specifies the physical address
+	range of the DCSR space.
+
+EXAMPLE
+	dcsr: dcsr@f00000000 {
+		#address-cells = <1>;
+		#size-cells = <1>;
+		compatible = "fsl,dcsr", "simple-bus";
+		ranges = <0x00000000 0xf 0x00000000 0x01008000>;

+Event Processing Unit
+
+This node represents the region of DCSR space allocated to the EPU
+
+PROPERTIES
+
+	- compatible
+	Usage: required
+	Value type: <string>
+	Definition: Must include "fsl,dcsr-epu"
+
+	- interrupts
+	Usage: required
+	Value type: <prop_encoded-array>
+	Definition:  Specifies the interrupts generated by the EPU.
+	The value of the interrupts property consists of three
+	interrupt specifiers. The format of the specifier is defined
+	by the binding document describing the node's interrupt parent.
+
+	The EPU counters can be configured to assert the performance
+	monitor interrupt signal based on either counter overflow or value
+	match. Which counter asserted the interrupt is captured in an EPU
+	Counter Interrupt Status Register (EPCPUISR).
+
+	The EPU unit can also be configured to assert either or both of
+	two interrupt signals based on debug event sources within the SoC.
+	The interrupt signals are epu_xt_int0 and epu_xt_int1.
+	Which event source asserted the interrupt is captured in an EPU
+	Interrupt Status Register (EPISR0,EPISR1).
+
+	Interrupt numbers are lised in order (perfmon, event0, event1).
+
+	- interrupt-parent
+	Usage: required

+The Freescale hypervisor and msi-address-64
+-------------------------------------------
+Normally, PCI devices have access to all of CCSR via an ATMU mapping.  The
+Freescale MSI driver calculates the address of MSIIR (in the MSI register
+block) and sets that address as the MSI message address.
+
+In a virtualized environment, the hypervisor may need to create an IOMMU
+mapping for MSIIR.  The Freescale ePAPR hypervisor has this requirement
+because of hardware limitations of the Peripheral Access Management Unit
+(PAMU), which is currently the only IOMMU that the hypervisor supports.
+The ATMU is programmed with the guest physical address, and the PAMU
+intercepts transactions and reroutes them to the true physical address.
+
+In the PAMU, each PCI controller is given only one primary window.  The
+PAMU restricts DMA operations so that they can only occur within a window.
+Because PCI devices must be able to DMA to memory, the primary window must
+be used to cover all of the guest's memory space.
+
+PAMU primary windows can be divided into 256 subwindows, and each
+subwindow can have its own address mapping ("guest physical" to "true
+physical").  However, each subwindow has to have the same alignment, which
+means they cannot be located at just any address.  Because of these
+restrictions, it is usually impossible to create a 4KB subwindow that
+covers MSIIR where it's normally located.
+
+Therefore, the hypervisor has to create a subwindow inside the same
+primary window used for memory, but mapped to the MSIR block (where MSIIR
+lives).  The first subwindow after the end of guest memory is used for
+this.  The address specified in the msi-address-64 property is the PCI
+address of MSIIR.  The hypervisor configures the PAMU to map that address to
+the true physical address of MSIIR.

+Under some circumstances a driver or subsystem may want to prevent a device
+from autosuspending immediately, even though the usage counter is zero and the
+autosuspend delay time has expired.  If the ->runtime_suspend() callback
+returns -EAGAIN or -EBUSY, and if the next autosuspend delay expiration time is
+in the future (as it normally would be if the callback invoked
+pm_runtime_mark_last_busy()), the PM core will automatically reschedule the
+autosuspend.  The ->runtime_suspend() callback can't do this rescheduling
+itself because no suspend requests of any kind are accepted while the device is
+suspending (i.e., while the callback is running).
+
 The implementation is well suited for asynchronous use in interrupt contexts.
 However such use inevitably involves races, because the PM core can't
 synchronize ->runtime_suspend() callbacks with the arrival of I/O requests.

+Converting old watchdog drivers to the watchdog framework
+by Wolfram Sang <w.sang@pengutronix.de>
+=========================================================
+
+Before the watchdog framework came into the kernel, every driver had to
+implement the API on its own. Now, as the framework factored out the common
+components, those drivers can be lightened making it a user of the framework.
+This document shall guide you for this task. The necessary steps are described
+as well as things to look out for.
+
+
+Remove the file_operations struct
+---------------------------------
+
+Old drivers define their own file_operations for actions like open(), write(),
+etc... These are now handled by the framework and just call the driver when
+needed. So, in general, the 'file_operations' struct and assorted functions can
+go. Only very few driver-specific details have to be moved to other functions.
+Here is a overview of the functions and probably needed actions:
+
+- open: Everything dealing with resource management (file-open checks, magic
+  close preparations) can simply go. Device specific stuff needs to go to the
+  driver specific start-function. Note that for some drivers, the start-function
+  also serves as the ping-function. If that is the case and you need start/stop
+  to be balanced (clocks!), you are better off refactoring a separate start-function.
+
+- close: Same hints as for open apply.
+
+- write: Can simply go, all defined behaviour is taken care of by the framework,
+  i.e. ping on write and magic char ('V') handling.
+
+- ioctl: While the driver is allowed to have extensions to the IOCTL interface,
+  the most common ones are handled by the framework, supported by some assistance
+  from the driver:
+
+	WDIOC_GETSUPPORT:
+		Returns the mandatory watchdog_info struct from the driver
+
+	WDIOC_GETSTATUS:
+		Needs the status-callback defined, otherwise returns 0
+
+	WDIOC_GETBOOTSTATUS:
+		Needs the bootstatus member properly set. Make sure it is 0 if you
+		don't have further support!
+
+	WDIOC_SETOPTIONS:
+		No preparations needed
+
+	WDIOC_KEEPALIVE:
+		If wanted, options in watchdog_info need to have WDIOF_KEEPALIVEPING
+		set
+
+	WDIOC_SETTIMEOUT:
+		Options in watchdog_info need to have WDIOF_SETTIMEOUT set
+		and a set_timeout-callback has to be defined. The core will also
+		do limit-checking, if min_timeout and max_timeout in the watchdog
+		device are set. All is optional.
+
+	WDIOC_GETTIMEOUT:
+		No preparations needed
+
+  Other IOCTLs can be served using the ioctl-callback. Note that this is mainly
+  intended for porting old drivers; new drivers should not invent private IOCTLs.
+  Private IOCTLs are processed first. When the callback returns with
+  -ENOIOCTLCMD, the IOCTLs of the framework will be tried, too. Any other error
+  is directly given to the user.
+
+Example conversion:
+
+-static const struct file_operations s3c2410wdt_fops = {
+-       .owner          = THIS_MODULE,
+-       .llseek         = no_llseek,
+-       .write          = s3c2410wdt_write,
+-       .unlocked_ioctl = s3c2410wdt_ioctl,
+-       .open           = s3c2410wdt_open,
+-       .release        = s3c2410wdt_release,
+-};
+
+Check the functions for device-specific stuff and keep it for later
+refactoring. The rest can go.
+
+
+Remove the miscdevice
+---------------------
+
+Since the file_operations are gone now, you can also remove the 'struct
+miscdevice'. The framework will create it on watchdog_dev_register() called by
+watchdog_register_device().
+
+-static struct miscdevice s3c2410wdt_miscdev = {
+-       .minor          = WATCHDOG_MINOR,
+-       .name           = "watchdog",
+-       .fops           = &s3c2410wdt_fops,
+-};
+
+
+Remove obsolete includes and defines
+------------------------------------
+
+Because of the simplifications, a few defines are probably unused now. Remove
+them. Includes can be removed, too. For example:
+
+- #include <linux/fs.h>
+- #include <linux/miscdevice.h> (if MODULE_ALIAS_MISCDEV is not used)
+- #include <linux/uaccess.h> (if no custom IOCTLs are used)
+
+
+Add the watchdog operations
+---------------------------
+
+All possible callbacks are defined in 'struct watchdog_ops'. You can find it
+explained in 'watchdog-kernel-api.txt' in this directory. start(), stop() and
+owner must be set, the rest are optional. You will easily find corresponding
+functions in the old driver. Note that you will now get a pointer to the
+watchdog_device as a parameter to these functions, so you probably have to
+change the function header. Other changes are most likely not needed, because
+here simply happens the direct hardware access. If you have device-specific
+code left from the above steps, it should be refactored into these callbacks.
+
+Here is a simple example:
+
++static struct watchdog_ops s3c2410wdt_ops = {
++       .owner = THIS_MODULE,
++       .start = s3c2410wdt_start,
++       .stop = s3c2410wdt_stop,
++       .ping = s3c2410wdt_keepalive,
++       .set_timeout = s3c2410wdt_set_heartbeat,
++};
+
+A typical function-header change looks like:
+
+-static void s3c2410wdt_keepalive(void)
++static int s3c2410wdt_keepalive(struct watchdog_device *wdd)
+ {
+...
++
++       return 0;
+ }
+
+...
+
+-       s3c2410wdt_keepalive();
++       s3c2410wdt_keepalive(&s3c2410_wdd);
+
+
+Add the watchdog device
+-----------------------
+
+Now we need to create a 'struct watchdog_device' and populate it with the
+necessary information for the framework. The struct is also explained in detail
+in 'watchdog-kernel-api.txt' in this directory. We pass it the mandatory
+watchdog_info struct and the newly created watchdog_ops. Often, old drivers
+have their own record-keeping for things like bootstatus and timeout using
+static variables. Those have to be converted to use the members in
+watchdog_device. Note that the timeout values are unsigned int. Some drivers
+use signed int, so this has to be converted, too.
+
+Here is a simple example for a watchdog device:
+
++static struct watchdog_device s3c2410_wdd = {
++       .info = &s3c2410_wdt_ident,
++       .ops = &s3c2410wdt_ops,
++};
+
+
+Register the watchdog device
+----------------------------
+
+Replace misc_register(&miscdev) with watchdog_register_device(&watchdog_dev).
+Make sure the return value gets checked and the error message, if present,
+still fits. Also convert the unregister case.
+
+-       ret = misc_register(&s3c2410wdt_miscdev);
++       ret = watchdog_register_device(&s3c2410_wdd);
+
+...
+
+-       misc_deregister(&s3c2410wdt_miscdev);
++       watchdog_unregister_device(&s3c2410_wdd);
+
+
+Update the Kconfig-entry
+------------------------
+
+The entry for the driver now needs to select WATCHDOG_CORE:
+
++       select WATCHDOG_CORE
+
+
+Create a patch and send it to upstream
+--------------------------------------
+
+Make sure you understood Documentation/SubmittingPatches and send your patch to
+linux-watchdog@vger.kernel.org. We are looking forward to it :)

-	  etc...) in one single integrated circuit. They usually talk to the
-	  main CPU through one or more IRQ lines and low speed data busses (SPI,

+        ---help---
+          This option allows you to select a number of media drivers that
+	  don't have the "normal" Linux kernel quality level.
+	  Most of them don't follow properly the V4L, DVB and/or RC API's,
+	  so, they won't likely work fine with the existing applications.
+	  That also means that, one fixed, their API's will change to match
+	  the existing ones.
+
+          If you wish to work on these drivers, to help improve them, or
+          to report problems you have with them, please use the
+	  linux-media@vger.kernel.org mailing list.
+
+          If in doubt, say N here.

+	  By default Squashfs sets the dev block size (sb_min_blocksize)

+	  (if larger).  This, because blocks are packed together and

+
+	  Using a 4K device block size may also improve overall I/O
+	  performance for some file access patterns (e.g. sequential
+	  accesses of files in filesystem order) on all media.
