Why is this here? I see the exact same line in videodev2.h.
Is this a leftover?

Looks good, additional defines apart

As I read this:
V4L2_PIX_FMT_BGRA555 VI6_FMT_BGRA_5551 LLS|LWS|WDS
gggrrrrr abbbbbgg bbbbbggg ggrrrrra ggrrrrra bbbbbggg
They seems different to me:
gggrrrrr abbbbbgg
ggrrrrra bbbbbggg
But I have not find any better combination from table 23.10 that would
result in the desired 'gggrrrrr abbbbbgg' ordering.

Same as above.
