The config APIs are used for config mmsys reg. Some mmsys regs need to be set according to the HW engine binding to the mmsys simultaneously. 1. mtk_mmsys_merge_async_config: config merge async width/height. async is used for cross-clock domain synchronization. 2. mtk_mmsys_hdr_confing: config hdr backend async width/height. 3. mtk_mmsys_mixer_in_config and mtk_mmsys_mixer_in_config: config mixer related settings.
