The cdn-dp sub driver probes the device failed on PINEBOOK Pro. kernel: cdn-dp fec00000.dp: [drm:cdn_dp_probe [rockchipdrm]] *ERROR* missing extcon or phy kernel: cdn-dp: probe of fec00000.dp failed with error -22
Then, the device halts all of the DRM related device jobs. For example, the operations: vop_component_ops, vop_component_ops and rockchip_dp_component_ops cannot be bound to corresponding devices. So, Xorg cannot find the correct DRM device. The USB type-C DisplayPort does not work for now. So, disable the DisplayPort node until the type-C phy work has been done.
