Subject: drm/rockchip: Add basic RK3588 HDMI output support
The RK3588 SoC family integrates the newer Synopsys DesignWare HDMI 2.1
Quad-Pixel (QP) TX controller IP and a HDMI/eDP TX Combo PHY based on a
Samsung IP block.
Add just the basic support for now, i.e. RGB output up to 4K@60Hz,
without audio, CEC or any of the HDMI 2.1 specific features.
