description: |
Rockchip RK3588 SoC integrates the Synopsys DesignWare HDMI QP TX controller
IP and a HDMI/eDP TX Combo PHY based on a Samsung IP block, providing the
following features, among others:
* Fixed Rate Link (FRL)
* Display Stream Compression (DSC)
* 4K@120Hz and 8K@60Hz video modes
* Variable Refresh Rate (VRR) including Quick Media Switching (QMS)
* Fast Vactive (FVA)
* SCDC I2C DDC access
* Multi-stream audio
* Enhanced Audio Return Channel (EARC)
