While working on enabling DSI support on rk3588 I stumbled across the issue of the display staying black while both the vop2 and dsi drivers were claiming to be running just fine.
After a bit of checking I found that I got DSI output on VP3 when HDMI on VP0 was at least associated in the DTS, but not without.
Andy's patch [0] helped and is definitly necessary, but did not fix the problem completely. The missing thing was that VP3 is rk3588-specific (rk3568 only has 3 video-ports, not 4 like rk3588) and the layers of VP3 never got configured.
Patch2 fixes this.
