From: Ville Syrjälä <ville.syrjala@xxxxxxxxxxxxxxx> Rebased pfit/scaler rework prep stuff. The eventual aim is to expose margin properties for external displays. Main use of which is to squish the image down a bit to avoid overscan on displays that insist on always overscanning. That will happen via the pfit/pipe scaler. And to avoid the user getting a black/corrupted screen we also need to add proper checks against various hw limits (scaling factors, pfit window coordinates, etc.). In fact we're already missing a bunch of checks for skl+ plane scaling cases (eg. the scaler simply doesn't work correctly with >4k resolutions so thos have to be rejected). Anyways, it's a fair amount of work so I'm posting it in smaller chunks.
