Hi All,
This patch series aims to add H265 pixel format (aka hevc).
High Efficiency Video Coding (HEVC), also known as H.265 and MPEG-H Part 2.
They describe the same video encoding method.
So for handling their behavior is the same.
However, when external camera device describes this encoding method,
some use hevc, some use h265.
There is no uniform specification to describe this encoding method.
So if an external camera device use h265 to describe this encoding method,
driver will not recognize it.
Therefore, this patch series aims to add H265 pixel format
to avoid this situation

Add H265 pixel format.
So driver can recognize external camera devices
whom use h265 to describe High Efficiency Video Coding method.

This is not yet defined I believe, so this patch needs to be 2/2 in this
series - with your following patch first so that they can both compile
independently.

I'd probably expect H265 to be sorted after H264 ? But I'm not sure this
list is sorted otherwise.

Please name this V4L2_PIX_FMT_HEVC. This has been discussed few years ago,
related to the staging V4L2_PIX_FMT_HEVC_SLICE format (which is being worked on
to be taken out of staging). HEVC was preferred over H.265, so lets be
consistent now that decision has been made.
