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

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

[Benjamin Gaignard]

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

[PATCH v2 7/7] media: hantro: Allows luma and chroma depth to be different

Luma and chroma depth are set on different hardware registers.
Even if they aren't identical the bitstream can be compliant
to HEVC specifications and decoded by the hardware.

With this patch TSUNEQBD_A_MAIN10_Technicolor_2 conformance test
is successfully decoded.

Hmm, the hantro driver will be unstaged either this week or (hopefully)
very early on in the next cycle. So I think you should no longer consider
hantro as a staging driver but as a regular mainline driver.

This series definitely won't make the 5.20 cut, so I think it makes more
sense to get this right before merging it.

Hmm, the hantro driver will be unstaged either this week or (hopefully)
