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.
