Subject[PATCH v4 4/4] media: cedrus: Add HEVC/H.265 decoding support
Date
This introduces support for HEVC/H.265 to the Cedrus VPU driver, with
both uni-directional and bi-directional prediction modes supported.

Field-coded (interlaced) pictures, custom quantization matrices and
10-bit output are not supported at this point.
