When decoding a 10bits bitstreams HEVC driver should only expose 10bits pixel formats. To fulfill this requirement it is needed to call hantro_reset_raw_fmt() and to only change driver internal state in case of success. Fluster score for HEVC (140/147) doesn't change after this series. Fluster score for VP9 is 146/303. version 8: - Correct patch 4. - Add a patch for VP9. version 7: - Remove unused ctx variable in hantro_try_ctrl(). - Change HANTRO_DEFAULT_BIT_DEPTH value to 8. - Simplify hantro_check_depth_match logic. - Keep ctx->bit_depth as integer value because it is use to compute buffers size for hevc. version 6: - Split the patches in multiple sub-patches. - Rework hantro_reset_encoded_fmt() usage. version 5: - Add Nicolas's review tags - Add Fixes tags version 4: - Split the change in 2 patches. - Change hantro_check_depth_match() prototype to avoid using ctx->bit_depth - Return the result of hantro_reset_raw_fmt() to the caller. - Only set ctx->bit_depth when hantro_reset_raw_fmt() returns is ok.
