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. And the drm architecture will select the appropriate format to change the dpi output.
