[PATCH 2/9] media: v4l2: Add NV12_16L16 pixel format to v4l2 format info
Posted by Paul Kocialkowski 2 years, 10 months ago
Represent the NV12_16L16 pixel format in the v4l2 format info table.
This is a 16x16 tiled version of NV12.

Not necessarily related to this patch, but I'm a bit puzzled by why
V4L2_PIX_FMT_NV12_4L4 doesn't list block sizes.

It looks like Ezequiel introduced that initially, but didn't introduce any tiled
format, as a side effect, we missed it and no one ever used it.

In practice, its not dramatic, since most of the time, the alignment needed is
bigger then the block (specially with only 4x4 tiles), but we should certainly
fix that, thanks for spotting.

Just to make sure this won't fall through the cracks, will you send a
patch ?

I didn't had any immediate plan to fix it (lack of time, absence of related
bugs). Andrzej, do you happen to have some time ? The SUNXI pixel format should
have that too, along with some NXP format.
