Allwinner H3 SoC has two mixers, one has 1 VI channel and 3 UI
channels,
and the other has 1 VI and 1 UI.
Add support for these two variants.

So the only difference between the two is the number of ui planes?
Not only., but currently we only implemented this.
More functions differ, but we still don't support them...
As far as I can tell, they only differ in ui & vi number of planes and between different SoCs, max plane size.
Icenowy, Do you know any other property they differ? I think everything else is based mostly on ui & vi number of planes.
Best regards, Jernej
Why not create a property to give the number then, instead of a compatible?
