Summary
Two fixes for RK3576 MIPI/DSI output when used alongside other displays.
Patches
drm/rockchip: rk3576: switch DSI dclk_src from vpll to cpll — When both DP and DSI are active, DP reprograms vpll which breaks DSI pixel clock. Switch DSI VP's dclk parent to cpll (1000MHz, supports 720x1280@60 exactly).
drm/rockchip: dw-mipi-dsi2: set panel orientation before device registration — Fixes when DSI panel driver calls from after DRM device registration.
