- Moved cdn-dp-reg from drivers/gpu/drm/rockchip to a new location in drivers/drm/bridge/cadence and renamed it to cdns-mhdp-common. - Extracted common fields from cdn_dp_device to a new cdns_mhdp_device structure which will be used by two separate drivers later on. - Moved some datatypes (audio_format, audio_info, vic_pxl_encoding_format, video_info) from cdn-dp-core.c to cdns-mhdp-common.h. - Changed prefixes from cdn_dp to cdns_mhdp cdn -> cdns to match the other Cadence's drivers dp -> mhdp to distinguish it from a "just a DP" as the IP underneath this registers map can be a HDMI (which is internally different, but the interface for commands, events is pretty much the same). - Modified cdn-dp-core.c to use the new driver structure and new function names. - Changed the CONFIG_ROCKCHIP_CDN_DP configuration to automatically select the Cadence MHDP DPI/DP bridge (DRM_CDNS_MHDP).
