Allwinner have a new "Display Engine 2.0" in their new SoCs, which comes with mixers to do graphic processing and feed data to TCON, like the old backends and frontends. Add support for the mixer on Allwinner V3s SoC; it's the simplest one. Currently a lot of functions are still missing -- more investigations are needed to gain enough information for them.
