4 Subject: [PATCH] drm/rockchip: prepare common code for cdns and rk dpi/dp
5 driver
6
7 - Extracted common fields from cdn_dp_device to a new cdns_mhdp_device
8 structure which will be used by two separate drivers later on.
9 - Moved some datatypes (audio_format, audio_info,
10 vic_pxl_encoding_format, video_info) from cdn-dp-core.c to cdn-dp-reg.h.
11 - Changed prefixes from cdn_dp to cdns_mhdp cdn -> cdns to match the other Cadence's drivers
12 dp -> mhdp to distinguish it from a "just a DP" as the IP underneath this registers map can be a HDMI (which is
13 internally different, but the interface for commands, events is pretty much the same).
14 - Modified cdn-dp-core.c to use the new driver structure and new function names.
