Define which HEVC profiles (up to level 5.1) and features
(no scaling, no 10 bits) are supported by the driver.

Silly nitpick. Looks like this is not defined yet?

I'm getting:

drivers/staging/media/hantro/hantro_drv.c:364:12: error: ‘HANTRO_HEVC_DECODER’ undeclared here (not in a function); did you mean
‘HANTRO_H264_DECODER’?

      |            ^~~~~~~~~~~~~~~~~~~
      |            HANTRO_H264_DECODER

I'll review the G2 driver soon :-)

Thanks,
