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].
