[PATCH 0/2] drm/rockchip: vop2: two fixes from working on DSI enablement

[Heiko Stuebner]

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.
