The Amlogic G12A SoC offers very close Video Display
functionnalities with it's older GXBB, GXL & GXM predecessors.

The main differences are :
- G12A Support now 3 "real" OSD planes with a new Blender module
- Instead of having a single Scaler for OSD1, G12A has two scaler
  that can be applied to 2 out of the 3 OSD planes or on the outputs
  of the blender module.
- The HDMI PHY now support RX-SENSE, Dynamic HDR and it's registers are
  now memory mapped instead of using an internal bus.
- The VPU now support a DSI interface to connect a display, using
  the Synopsys DSI controller and a custom PHY

The complex Blender routing, HDMI RX-SENSE, Dynamic HDR and DSI support
are not handled in this patchset.

This patchset implements on-par support with the currently support
GXBB, GXL and GXM SoCs. There is no support delta with this patchset.

patch 10 & 11 implements the bindings found at [1].
