* V4L/DVB: saa7146: fix regression of the av7110/budget-av driverHans Verkuil2010-05-06
| | | | | | | | | | | | | | | | | | | An earlier regression fix for the mxb driver (V4L/DVB: saa7146_vv: fix regression where v4l2_device was registered too late) caused a new regression in the av7110 driver. Reverted the old fix and fixed the problem in the mxb driver instead. Tested on mxb and budget-av cards. The real problem is that the saa7146 framework has separate probe() and attach() driver callbacks which should be rolled into one. This is now done for the mxb driver, but others should do the same. Lack of hardware makes this hard to do, though. I hope to get hold of some hexium cards and then I can try to improve the framework to prevent this from happening again.

* V4L/DVB: saa7146_vv: fix regression where v4l2_device was registered too lateHans Verkuil2010-02-26
| | | | | | | | | | | | | | v4l2_device_register needs to be called before the i2c subdevs are loaded. However, it was called afterwards in the saa7146 driver. This caused an oops when loading the mxb and hexium drivers. The vv_init function is now split into two: one registers the v4l2_device, the other does the rest of the initialization. The three drivers that depend on this have been updated to call the new vv_devinit function. Thanks to Michael Hunold for reporting this.

* V4L/DVB (13557): v4l: Remove unneeded video_device::minor usage in driversLaurent Pinchart2009-12-15
| | | | | | | | | | | | | | | | The video_device::minor field is used where it shouldn't, either to - test for error conditions that can't happen anymore with the current v4l-dvb core, - store the value in a driver private field that isn't used anymore, - check the video device type where video_device::vfl_type should be used, or - create the name of a kernel thread that should get a stable name. Remove or fix those use cases. Signed-off-by: Laurent Pinchart <laurent.pinchart@ideasonboard.com> Signed-off-by: Mauro Carvalho Chehab <mchehab@redhat.com>
* V4L/DVB (10271): saa7146: convert to video_ioctl2.Hans Verkuil2009-03-30

* V4L/DVB (10138): v4l2-ioctl: change to long return type to match unlocked_ioctl.Hans Verkuil2009-01-02
| | | | | | | | | | | | | Since internal to v4l2 the ioctl prototype is the same regardless of it being called through .ioctl or .unlocked_ioctl, we need to convert it all to the long return type of unlocked_ioctl. Thanks to Jean-Francois Moine for posting an initial patch for this and thus bringing it to our attention.

* V4L/DVB (10135): v4l2: introduce v4l2_file_operations.Hans Verkuil2009-01-02
| | | | | | | | | | | | | | | | Introduce a struct v4l2_file_operations for v4l2 drivers. Remove the unnecessary inode argument. Move compat32 handling (and llseek) into the v4l2-dev core: this is now handled in the v4l2 core and no longer in the drivers themselves. Note that this changeset reverts an earlier patch that changed the return type of__video_ioctl2 from int to long. This change will be reinstated later in a much improved version.

* V4L/DVB (9503): v4l: remove inode argument from video_usercopyHans Verkuil2008-12-29
| | | | | | | | | The inode argument was never used. Removing it from video_usercopy brings the function pointer type of video_usercopy in line with similar v4l2 functions, thus simplifying several drivers.

| | | | | | | | | | | | | v4l2-common.h or v4l2-ioctl.h The functions in a header should not belong to another module. The prio functions belong to v4l2-common.c, so move them to v4l2-common.h. The ioctl functions belong to v4l2-ioctl.c, so create a new v4l2-ioctl.h header and move those functions to it.

* V4L/DVB (6252): Adapt drivers to use the newer videobuf modulesMauro Carvalho Chehab2007-10-09
| | | | | | | | | | | | | | PCI-dependent videobuf_foo methods were renamed as videobuf_pci_foo. Also, videobuf_dmabuf is now part of videobuf-dma-sg private struct. So, to access it, a subroutine call is needed. This patch renames all occurences of those function calls to be consistent with the video-buf split.

* V4L/DVB (5441): Saa7146: Fix allocation of clipping memoryOliver Endriss2007-03-27
| | | | | | | | | | | | | Olaf Hering pointed out that SAA7146_CLIPPING_MEM would become very large for PAGE_SIZE > 4K. In fact, the number of clipping windows is limited to 16, and calculate_clipping_registers_rect() does not use more than 256 bytes. SAA7146_CLIPPING_MEM adjusted accordingly.

| | | | | | | | | | | | | | videodev2.h The videodev.h and videodev2.h describe the public API for V4L and V4L2. It shouldn't have there any kernel-specific stuff. Those were moved to v4l2-dev.h. This patch removes some uneeded headers and include v4l2-common.h on all V4L driver. This header includes device implementation of V4L2 API provided on v4l2-dev.h as well as V4L2 internal ioctls that provides connections between master driver and its i2c devices.

* V4L/DVB (3516): Make video_buf more genericMauro Carvalho Chehab2006-03-24
| | | | | | | | | | | Video_buf were concerned to allow PCI devices to be used as video capture devices. This patch extends video_buf features by virtualizing pci-dependent functions and allowing other type of devices to use it. It is still DMA centric, although it may be used also by devices that emulates scatter/gather behavior or a DMA device Signed-off-by: Mauro Carvalho Chehab <mchehab@infradead.org>

Initial git repository build. I'm not bothering with the full history, even though we have it. We can create a separate "historical" git archive of that later if we want to, and in the meantime it's about 3.2GB when imported into git - space that would just make the early git days unnecessarily complicated, when we don't have a lot of good infrastructure for it. Let it rip!
