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. Patches 1-5 fix a few compliance issues with the decoder and encoder, most notably by adding support for the START and STOP command for the latter. These patches were last up until v4 but have been moved to the beginning so they can be applied sooner. Patches 6-9 separates the "stateful" part of the driver into its own file and add support for the new firmware and pixel format used by MT8183. Patches 10-14 add support for H.264 stateless decoding and MT8183. Note that a few checkpatch issues have been left unadressed on purpose: * Conversion from e.g. uint32_t to u32 can't be done without breaking consistency. This should be done by a driver-wide patch. * Some macro warning suggesting parentheses for parameters expanded as struct members, which is obviously not applicable here. * Warnings about adding new files without an update the MAINTAINERS, which is irrelevant as the new files are already covered by the existing wildcards. Changes since v5: * Rebased against latest media tree. * Applied most suggestions of `checkpatch.pl --strict`. Some proposed fixes were not applied because they would require a larger refactoring (i.e. large-scale type changes) of the code. * Applied Reviewed-by and fix suggestions from Tzung-bi. * Check for ABORT state in vidioc_encoder_cmd. Changes since v4: * Reorganized fixup patches first. * Select MEDIA_CONTROLLER_REQUEST_API. * Properly capitalize MM21's format description string. * Reorganize stateless code as suggested by Hans. * Fix compilation errors when DEBUG is defined. * Merge double-free fixup patch into the patch that introduced the issue. Changes since v3: * Stop checking that controls are set for every request. * Add V4L2_CID_STATELESS_H264_START_CODE control. * Stop mapping OUTPUT buffers and getting the NAL type from them, use the nal_ref_idc field instead. * Make V4L2_CID_MIN_BUFFERS_FOR_CAPTURE control stateful-only. * Set vb2_buffer's field to V4L2_FIELD_NONE in buffer validation hook. Changes since v2: * Add follow-up patches fixing support for START/STOP commands for the encoder, and stateful decoder.
