The one handled in this series should get the eDP port running, which is routed to the "eDP Panel" in the block diagram on page 3 of the Rock 5 ITX schematics. So this series adds support for using "HDMI/eDP TX0" and "HDMI/eDP TX1" in DP mode. The port routed to HDMI0 via RA620 is the other DP controller, which also exists twice: "TYPEC0/DP0" and "TYPEC1/DP1". This DP controller is not yet supported upstream and there is no pending patchset. As far as I know Rockchip plans to work on preparing upstream support for that soon. Note, that the two DisplayPort controllers are completely different. The HDMI/eDP controller is a design from Analogix and the TypeC/DP controller is a design from Synopsys. P.S.: Heiko merged support for HDMI1 (RK3588 SoC level) recently. So you should be able to get that running by some DT additions to the Rock 5 ITX board DT with the latest linux-next code :) Greetings, -- Sebastian
