2010-10-21[media] SoC Camera: add driver for OV6650 sensorJanusz Krzysztofik
This patch provides a V4L2 SoC Camera driver for OV6650 camera sensor, found on OMAP1 SoC based Amstrad Delta videophone. Since I have no experience with camera sensors, and the sensor documentation I was able to find was not very comprehensive, I left most settings at their default (reset) values, except for: - those required for proper mediabus parameters and picture geometry and format setup, - those used by controls. Resulting picture quality may be far from perfect, but better than nothing. In order to be able to get / set the sensor frame rate from userspace, I decided to provide two not yet SoC camera supported operations, g_parm and s_parm. These can be used after applying patch 4/6 from this series, "SoC Camera: add support for g_parm / s_parm operations". Created and tested against linux-2.6.36-rc5 on Amstrad Delta.

2010-10-21[media] SoC Camera: add driver for OMAP1 camera interfaceJanusz Krzysztofik
This is a V4L2 driver for TI OMAP1 SoC camera interface. Both videobuf-dma versions are supported, contig and sg, selectable with a module option. The former uses less processing power, but often fails to allocate contignuous buffer memory. The latter is free of this problem, but generates tens of DMA interrupts per frame. If contig memory allocation ever fails, the driver falls back to sg automatically on next open, but still can be switched back to contig manually. Both paths work stable for me, even under heavy load, on my OMAP1510 based Amstrad Delta videophone, that is the oldest, least powerfull OMAP1 implementation. The interface generally works in pass-through mode. Since input data byte endianess can be swapped, it provides up to two v4l2 pixel formats per each of several soc_mbus formats that have their swapped endian counterparts. Boards using this driver can provide it with the following platform data: - if and what freqency clock is expected by an on-board camera sensor, - what is the maximum pixel clock that should be accepted from the sensor, - what is the polarity of the sensor provided pixel clock, - if the interface GPIO line is connected to a sensor reset/powerdown input and what is the input polarity. Created and tested against linux-2.6.36-rc5 on Amstrad Delta.

2010-10-21[media] IR/lirc: further ioctl portability fixupsJarod Wilson
>From Joris van Rantwijk <jorispubl@xs4all.nl>: I tested lirc_serial and found that it works fine. Except the LIRC ioctls do not work in my 64-bit-kernel/32-bit-user setup. I added compat_ioctl entries in the drivers to fix this. While doing so, I noticed inconsistencies in the argument type of the LIRC ioctls. All ioctls are declared in lirc.h as having argument type __u32, however there are a few places where the driver calls get_user/put_user with an unsigned long argument. The patch below changes lirc_dev and lirc_serial to use __u32 for all ioctl arguments, and adds compat_ioctl entries. It should probably also be done in the other low-level drivers, but I don't have hardware to test those. I've dropped the .compat_ioctl addition from Joris' original patch, as I swear the non-compat definition should now work for both 32-bit and 64-bit userspace. Technically, I think we still need/want a in getting a reply to you).

Currently videobuf uses the vb_lock mutex to lock its data structures. But this locking will (optionally) move into the v4l2 core, which means that in that case vb_lock shouldn't be used since the external lock is already held.

Drivers can optionally set a pointer to a mutex in struct video_device. The core will use that to lock before calling open, read, write, unlocked_ioctl, poll, mmap or release. Updated the documentation as well and ensure that v4l2-event knows about the lock: it will unlock it before doing a blocking wait on an event and relock it afterwards. Ensure that the 'video_is_registered' check is done when the lock is held: a typical disconnect will take the lock as well before unregistering the device nodes, so to prevent race conditions the video_is_registered check should also be done with the lock held.

Trivial extraction from David Härdeman's pending rc-core merge and device interface abstraction patchset to facilitate merging a patch based on his imon input dev split patch ahead of the larger churn, which is slated for post-2.6.37-rc1 (after Dmitry's large keycode patches are merged in mainline).

The include/media/v4l2-i2c-drv.h header was used to be able to compile drivers in the v4l-dvb hg repository for legacy kernels (mainly pre-2.6.26) without creating an #ifdef mess. The hg repository dropped support for kernels < 2.6.26 so we can remove this header. All i2c drivers that used it have now been converted to use proper i2c code. The header was a hack, but it did its job well.

2010-10-21V4L/DVB: videotext: remove this obsolete APIHans Verkuil
Remove the vtx (aka videotext aka teletext) API from the v4l2 core. This API was scheduled for removal in kernel 2.6.35. The vtx device nodes have been superseded by vbi device nodes for many years. No applications exist that use the vtx support. Of the two i2c drivers that actually support this API the saa5249 has been impossible to use for a year now and no known hardware that supports this device exists. The saa5246a is theoretically supported by the old mxb boards, but it never actually worked. In summary: there is no hardware that can use this API and there are no applications actually implementing this API. The vtx support still reserves minors 192-223 and we would really like to reuse those for upcoming new functionality. In the unlikely event that new hardware appears that wants to use the functionality provided by the vtx API, then that functionality should be build around the sliced VBI API instead.

2010-10-21V4L/DVB: IR/streamzap: functional in-kernel decodingJarod Wilson
This patch makes in-kernel decoding with the stock Streamzap PC Remote work out of the box. There are quite a few things going on in this patch, all related to getting this working: 1) I had to enable reporting of a long space at the end of each signal, or I had weird buffering and keybounce issues. 2) The keymap has been reworked slightly to match actual decoded values, the first edition was missing the pre-data bits present in the lirc config file for this remote. 3) There's a whole new decoder included, specifically for the not-quite-RC5 15-bit protocol variant used by the Streamzap PC Remote. The decoder, while usable with other recievers (tested with an mceusb receiver), will only be loaded by the streamzap driver, as its likely not of use in almost all other situations. This can be revisited if/when all keytable loading (and disabling of unneeded protocol decoder engines) is moved to userspace, but for now, I think this makes the most sense. Note that I did try to enable handling the streamzap RC5-ish protocol in the current RC5 decoder, but there's no particularly easy way to tell if its 14-bit RC5 or 15-bit Streamzap until we see bit 14, and even then, in testing an attempted decoder merge, only 2/3 of the keys were properly recognized as being the 15-bit variant and decoded correctly, the rest were close enough to compliant with 14-bit that they were decoded as such (but they have overlap with one another, and thus we can't just shrug and use the 14-bit decoded values). Also of note in this patch is the removal of the streamzap driver's internal delay buffer. Per discussion w/Christoph, it shouldn't be needed by lirc any longer anyway, and it doesn't seem to make any difference to the in-kernel decoder engine. That being the case, I'm yanking it all out, as it greatly simplifies the driver code. Signed-off-by: Jarod Wilson <jarod@redhat.com> Signed-off-by: Mauro Carvalho Chehab <mchehab@redhat.com>

2010-09-28V4L/DVB: videobuf-dma-sg: set correct size in last sg elementHans Verkuil
This fixes a nasty memory corruption bug when using userptr I/O. The function videobuf_pages_to_sg() sets up the scatter-gather list for the DMA transfer to the userspace pages. The first transfer is setup correctly (the size is set to PAGE_SIZE - offset), but all other transfers have size PAGE_SIZE. This is wrong for the last transfer which may be less than PAGE_SIZE. Most, if not all, drivers will program the boards DMA engine correctly, i.e. even though the size in the last sg element is wrong, they will do their own size calculations and make sure the right amount is DMA-ed, and so seemingly prevent memory corruption. However, behind the scenes the dynamic DMA mapping support (in lib/swiotlb.c) may create bounce buffers if the memory pages are not in DMA-able memory. This happens for example on a 64-bit linux with a board that only supports 32-bit DMA. These bounce buffers DO use the information in the sg list to determine the size. So while the DMA engine transfers the correct amount of data, when the data is 'bounced' back too much is copied, causing buffer overwrites. The fix is simple: calculate and set the correct size for the last sg list element.

2010-08-09V4L/DVB: v4l2: Add new control handling frameworkHans Verkuil
Add a new framework to handle controls which makes life for driver developers much easier. Note that this patch moves some of the control support that used to be in v4l2-common.c to v4l2-ctrls.c. The tables were copied unchanged. The body of v4l2_ctrl_query_fill() was copied to a new v4l2_ctrl_fill() function in v4l2-ctrls.c. This new function doesn't use the v4l2_queryctrl struct anymore, which makes it more general. The remainder of v4l2-ctrls.c is all new. Highlights include: - No need to implement VIDIOC_QUERYCTRL, QUERYMENU, S_CTRL, G_CTRL, S_EXT_CTRLS, G_EXT_CTRLS or TRY_EXT_CTRLS in either bridge drivers or subdevs. New wrapper functions are provided that can just be plugged in. Once everything has been converted these wrapper functions can be removed as well. - When subdevices are added their controls can be automatically merged with the bridge driver's controls. - Most drivers just need to implement s_ctrl to set the controls. The framework handles the locking and tries to be as 'atomic' as possible. - Ready for the subdev device nodes: the same mechanism applies to subdevs and their device nodes as well. Sub-device drivers can make controls local, preventing them from being merged with bridge drivers. - Takes care of backwards compatibility handling of VIDIOC_S_CTRL and VIDIOC_G_CTRL. Handling of V4L2_CID_PRIVATE_BASE is fully transparent. CTRL_CLASS controls are automatically added.

2010-08-09V4L/DVB: staging/lirc: port lirc_streamzap to ir-coreJarod Wilson
This ports lirc_streamzap.c over to ir-core in-place, to be followed by a patch moving the driver over to drivers/media/IR/streamzap.c and enabling the proper Kconfig bits. Presently, the in-kernel keymap doesn't work, as the stock Streamzap remote uses an RC-5-like, but not-quite-RC-5 protocol, which the in-kernel RC-5 decoder doesn't cope with. The remote can be used right now with the lirc bridge driver though, and other remotes (at least an RC-6(A) MCE remote) work perfectly with the driver. I'll take a look at making the existing RC-5 decoder cope with this odd duck, possibly implement another standalone decoder engine, or just throw up my hands and say "meh, use lirc"... But the driver itself should be perfectly sound. Remaining items on the streamzap TODO list: - add LIRC_SET_REC_TIMEOUT-alike support - add LIRC_GET_M{AX,IN}_TIMEOUT-alike support - add LIRC_GET_REC_RESOLUTION-alike support All of the above should be trivial to add. There are patches pending to add this support to ir-core from Maxim Levitsky, and I'll take care of these once his patches get integrated. None of them are currently essential though.

2010-08-09V4L/DVB: v4l2_subdev: Move interrupt_service_routine ptr to v4l2_subdev_core_opsAndy Walls
The CX2584x and related cores are multifunction subdevices with a number of internal blocks that act as interrupt sources. Move the v4L2_subdev interrupt_service_routine callback from v4l_subdev_ir_ops to v4l2_subdev_core_ops, as the video and audio blocks of a CX2584x and related cores can generate interrupts along with the IR block. This change also makes sense for other subdev's that generate interrupts and do not have an IR block.

2010-08-09V4L/DVB: v4l2_subdev, cx23885: Differentiate IR carrier sense and I/O pin ↵Andy Walls
inversion There is a distinction on IR Tx for the CX2388[578] chips of carrier sense inversion (space is a carrier burst and mark is no burst) and I/O pin level inversion (0 is high output level, 1 is low output level). Allow the caller to set these parameters distinctly as v4l2_subdevice IR parameters. This permits the IR device to be configured and enabled without the IR Tx LED being on during idle/space time due to an external hardware level inversion Signed-off-by: Andy Walls <awalls@md.metrocast.net> Signed-off-by: Mauro Carvalho Chehab <mchehab@redhat.com>
