RK3576 integrates the Analogix eDP 1.3 TX controller IP and the HDMI/eDP
TX Combo PHY based on a Samsung IP block - both of which are the same as
those on RK3588.
The patch currently adds only the basic support, specifically RGB output
up to 4K@60Hz, without the tests for audio, PSR and other eDP 1.3 specific
features.
