[media] videodev2.h: go back to limited range Y'CbCr for SRGB and, ADOBERGB

2017-02-13T16:33:56+00:00

This reverts 'commit 7e0739cd9c40 ("[media] videodev2.h: fix
sYCC/AdobeYCC default quantization range").

The problem is that many drivers can convert R'G'B' content (often
from sensors) to Y'CbCr, but they all produce limited range Y'CbCr.

To stay backwards compatible the default quantization range for
sRGB and AdobeRGB Y'CbCr encoding should be limited range, not full
range, even though the corresponding standards specify full range.

Update the V4L2_MAP_QUANTIZATION_DEFAULT define accordingly and
also update the documentation.

[media] rc: change wakeup_protocols to list all protocol variants

2017-01-30T14:15:12+00:00

For IR wakeup, a driver has to program the hardware to wakeup at a
specific IR sequence, so it makes no sense to allow multiple wakeup
protocols to be selected. In the same manner the sysfs interface only
allows one scancode to be provided.

In addition, we need to know the specific variant of the protocol.

In short, these changes are made to the wakeup_protocols sysfs entry:
 - list all the protocol variants rather than the protocol groups,
   e.g. "nec nec-x nec-32" rather than just "nec".
 - only allow one protocol variant to be selected rather than multiple
 - wakeup_filter can only be set once a protocol has been selected in
   wakeup_protocols.

This is an API change, however the only user of this API is the img-ir,
but the wakeup code was never merged to mainline, so it was never used.
