From: Ville Syrjälä <[email protected]> Pre-icl doesn't use a separate hardware plane for Y scanout, and instead it's all handled magially by the hardware. We do still need to allocate DDB space for the Y color plane though (PLANE_NV12_BUF_CFG). Include that information in the debugs so that we know where it ended up.
On icl+ the equivalent information is dumped as the hardware Y plane's normal ddb allocation.
