Diederik,
Thx for looking on this.
Im afraid patch will not make hdmi0 working as rock5 itx board has hdmi0 designed to use 3588 eDP1 + eDP->HDMI converter (in-house developed rk620 chip).
I suspect we need:
-enable eDP1 support (hope Damon code can do this easily)
-map eDP to port0 in vop2 (port1 should be mapped to eDP/HDMI tx1)
-set typeC1/eDP1 mux to eDP1
Then maybe we should have hdmi0 working?
Im curious a bit about vop port mappings: maybe we can go with generic approach like:
eDP/HDMI tx0 -> port0
eDP/HDMI tx1 -> port1
typeC0/eDP0 -> port2 (+ exception for for rock5 itx: typeC1/eDP1 -> port2)
