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
