Here is the second version is this patchset, although there has been such a delay after the first one that probably nobody remembers it has even been sent. This series adds support for the stateless API into mtk-vcodec, by first separating the stateful ops into their own source file, and introducing a new set of ops suitable for stateless decoding. As such, support for stateful decoders should remain completely unaffected. This series has been tested with both MT8183 and MT8173. Decoding was working for both chips, and in the case of MT8173 no regression has been spotted. v4l2-compliance is also passing, minor a problem when testing requests on MT8183: the test tries to call S_EXT_CTRLS on the first available control, which happens to be V4L2_CID_MIN_BUFFERS_FOR_CAPTURE. Since this control is read-only, the driver returns -EACCESS. I suppose this is a problem with v4l2-compliance and not the driver.
