|     phy: rockchip: Add Samsung HDMI/eDP Combo PHY driver
|
|     Add driver for the HDMI/eDP TX Combo PHY found on Rockchip RK3588 SoC.
|
|     The PHY is based on a Samsung IP block and supports HDMI 2.1 TMDS, FRL
|     and eDP links.  The maximum data rate is 12Gbps (FRL), while the minimum
|     is 250Mbps (TMDS).
|
|     Only the TMDS link is currently supported.
