However, on RK3288 and PX30 VOPB is gets registered as crtc-0 instead of VOPL. With VOPL registered as crtc-0 the kernel kms client is not able to enable 4K display modes for console use on RK3399. Load VOPB before VOPL to help kernel kms client make use of 4K display modes for console use on RK3399.
