* V4L/DVB (8787): v4l2-dev: cleanups and add video_drvdata helper functionHans Verkuil2008-10-122-21/+27
| | | | | | | | | Cleanup v4l2-dev.[ch], add/improve comments and add a new helper function: video_drvdata() that can get the private driver data from a file struct. Signed-off-by: Hans Verkuil <hverkuil@xs4all.nl> Signed-off-by: Mauro Carvalho Chehab <mchehab@redhat.com>

* V4L/DVB (8784): v4l2-dev: make the video_device's release callback mandatoryHans Verkuil2008-10-121-14/+2
| | | | | | | | | Now that all drivers set the release callback in the video_device struct we can put in a BUG_ON in video_register_device to ensure that the callback is always there. Signed-off-by: Hans Verkuil <hverkuil@xs4all.nl> Signed-off-by: Mauro Carvalho Chehab <mchehab@redhat.com>

| | | | | | | | | | | | Add a second release function: video_device_release_empty It can be used by drivers that have statically allocated video_device structs.

* V4L/DVB (8774): cx18: Have CX23418 release buffers at end of capture.Andy Walls2008-10-123-1/+12
| | | | | | | | | | | | cx18: Have CX23418 release buffers at end of capture. The CX23418 reuses task handles so we need to have it release the buffers associated with a task handle at the end of a capture. If we don't, buffer ids used for one type of stream in the driver (MPEG, TS, PCM), could be used for another type of stream by the CX23418, if a previously used handle is assigned to a different type of stream. The driver would drop valid buffers when this happened. Signed-off-by: Andy Walls <awalls@radix.net> Signed-off-by: Mauro Carvalho Chehab <mchehab@redhat.com>

| | | | | | | | | | | | | | | | | | | | | | (rev 2) Add support for revision 2 of the DViCO FusionHDTV DVB-T Dual Digital 4 which has new tuners and demodulators (2 x DIB7070p). With this patch both DVB reception and IR works. The dib7000p driver currently hardwires the output mode to OUTMODE_MPEG2_SERIAL regardless of what we ask for. Modify it to allow OUTMODE_MPEG2_PAR_GATED_CLK to be set. Longer term we should remove the check completely and set the output mode correctly in all the callers. Add Kconfig bits to ensure the dib7000p and dib0070 modules are enabled. It would be nice to only do this for the !DVB_FE_CUSTOMISE case, but this is what the other DIB7070 module does (there are a number of module dependencies in the attach code).
