Subject: [PATCH v2 0/7]  Enable 10bits bitstream for Hantro/G2 HEVC codec

Since v1 Jernej patches to support 10 bits decoding have been merged.
This v2 rebase the previously send patches and add Ezequiel reviewed-by
tag.
This series add 10bits support for newer hardware blocks (i.e without
legacy regs) and for HEVC codec.

It based tested on IMX8MQ with HEVC conformance tests.
The results are that all 10bits bitstreams are OK.

The problematic point raise by this series is the question of where 
to put HEVC validation function. Does it have to be only hantro_try_ctrl()
or shall it be done also in .run().
This series doesn't change that behavoir so I will argue in farvor to
merge it and to work on this validation time problem when unstaging 
the driver.
Hans, Ezequiel may that sound acceptable for you ? 

Regards,
Benjamin
