2016-09-09[media] doc-rst: 16-bit BGGR is always 16 bitsSakari Ailus1-5/+0
The V4L2_PIX_FMT_SBGGR16 format is documented to contain samples of fewer than 16 bits. However, we do have specific definitions for smaller sample sizes. Therefore, this note is redundant from the API point of view. Currently only two drivers, am437x and davinci, use the V4L2_PIX_FMT_SBGGR16 pixelformat currently. The sampling precision is understood to be 16 bits in all current cases. Remove the note on sampling precision.

2016-09-09[media] doc-rst: Correct the ordering of LSBs of the 10-bit raw packed formatsSakari Ailus1-8/+8
The 10-bit packed raw bayer format documented that the data of the first pixel of a four-pixel group was found in the first byte and the two highest bits of the fifth byte. This was not entirely correct. The two bits in the fifth byte are the two lowest bits. The second pixel occupies the second byte and third and fourth least significant bits and so on.

2016-09-09[media] fix broken references on dvb/video*rstMauro Carvalho Chehab12-5/+157
Trivially fix those broken references, by copying the structs fron the header, just like other API documentation at the DVB side. This doesn't have the level of quality used at the V4L2 side of the API, but, as this documents a deprecated API, used only by av7110 driver, it doesn't make much sense to invest time making it better.
