2016-11-16[media] cobalt: add cropcap supportHans Verkuil1-0/+21
Now that the timings contain picture aspect ratio information, we can support cropcap to return the pixel aspect ratio. Signed-off-by: Hans Verkuil <hans.verkuil@cisco.com> Signed-off-by: Mauro Carvalho Chehab <mchehab@s-opensource.com>

2016-11-16[media] hdpvr: fix interrupted recordingJonathan Sims1-3/+19
This is a reworking of a patch originally submitted by Ryley Angus, modified by Hans Verkuil and then seemingly forgotten before changes suggested by Keith Pyle here: http://www.mail-archive.com/linux-media@vger.kernel.org/msg75163.html were made and tested. I have implemented the suggested changes and have been testing for the last 2 months. I am no longer experiencing lockups while recording (with blue light on, requiring power cycling) which had been a long standing problem with the HD-PVR. I have not noticed any other problems since applying the patch.

2016-11-16[media] media: solo6x10: fix lockup by avoiding delayed register writeAndrey Utkin1-0/+3
This fixes a lockup at device probing which happens on some solo6010 hardware samples. This is a regression introduced by commit e1ceb25a1569 ("[media] SOLO6x10: remove unneeded register locking and barriers") The observed lockup happens in solo_set_motion_threshold() called from solo_motion_config(). This extra "flushing" is not fundamentally needed for every write, but apparently the code in driver assumes such behaviour at last in some places. Actual fix was proposed by Hans Verkuil.
