2014-03-11[media] omap_vout: Add DVI display type supportLaurent Pinchart1-0/+1
Since the introduction of the new OMAP DSS DVI connector driver in commit 348077b154357eec595068a3336ef6beb870e6f3 ("OMAPDSS: Add new DVI Connector driver"), DVI outputs report a new display type of OMAP_DISPLAY_TYPE_DVI instead of OMAP_DISPLAY_TYPE_DPI. Handle the new type in the IRQ handler.

Struct v4l2_subdev_edid and the VIDIOC_SUBDEV_G/S_EDID ioctls were specific for subdevices, but for hardware with a simple video pipeline you do not need/want to create subdevice nodes to just get/set the EDID. Move the v4l2_subdev_edid struct to v4l2-common.h and rename as v4l2_edid. Add the same ioctls to videodev2.h as well, thus allowing this API to be used with both video nodes and v4l-subdev nodes.

interruptible_sleep_on is racy and going away. In the arv driver that race has probably never caused problems since it would require a whole video frame to be captured before the read function has a chance to go to sleep, but using wait_event_interruptible lets us kill off the old interface. In order to do this, we have to slightly adapt the meaning of the ar->start_capture field to distinguish between not having started a frame and having completed it.

It is not clear how to get the packet count for QAM. So, for now, don't expose PER for QAM. Signed-off-by: Mauro Carvalho Chehab <m.chehab@samsung.com>
2014-03-11[media] drx-j: Prepare to use DVBv5 statsMauro Carvalho Chehab2-220/+125
Convert the stats internally to use DVBv5. For now, it will keep showing everything via DVBv3 API only, as the .len value were not initialized. That allows testing if the new stats code didn't break anything. A latter patch will add the final bits for the DVBv5 stats to fully work. Signed-off-by: Mauro Carvalho Chehab <m.chehab@samsung.com>
