Because different sink ICs may support other output formats. The current DRM architecture supports retrieving the output format of all bridges (eg dpi is implemented via DRM's .atomic_check and .atomic_get_output_bus_fmts and .atomic_get_input_bus_fmts). If no unified output format is found, the default soc format (MEDIA_BUS_FMT_RGB888_2X12_LE in mt8186) is used. Therefore, if there are other format sink ICs (RGB888_DDR/RGB888_SDR) in the future, the sink IC needs to add the func implementation mentioned above needs to be added.=20 And the drm architecture will select the appropriate format to change the dpi output.
