Hi,

This series adds support for R-Car Gen3 VIN Up Down Scaler (UDS) on 
those SoCs that supports it.

Patch 1/3 prepares the VIN driver selection rectangles to work with the
media controller part of the driver. Patch 2/3 then do the plumbing to 
allow more then one scaler implementation. Finally patch 3/3 adds 
support for the Gen3 UDS scaler.

The series is based on top of media-tree/master and is tested on both 
Gen3 and Gen2 without finding any regressions.

Niklas Söderlund (3):
  media: rcar-vin: Do not cache remote rectangle
  media: rcar-vin: Store scaler in a function pointer
  media: rcar-vin: Add support for Gen3 UDS (Up Down Scaler)
