Hello,

Sorry for the noise, I forgot to Cc the DT maintainers/ML on my last
attempt.

This is v2 of the rkvdec driver which was initially posted as part of
my RFC adding codec helpers.
For this version, I decided to get rid of the helper stuff which is
likely to take some more time to settle. The patchset now contains a
proper DT binding doc.

Note that this implementation is likely to be adjusted based on the
outcome of the 'scaling matrix order' [1] and 'dynamic resolution
changes' [2] discussions, but I thought it'd be worth posting this
version to start getting feeback.

Regards,

Boris

I assume this version of the driver does not (yet?) support slicing?

Core slicing support is part of this series:

Nope, but the driver does not support SLICE_BASED decoding anyway, so
I'm not sure slicing applies here.
