 Required properties:
   - compatible: value must be one of:
     * allwinner,sun8i-v3s-de2-mixer

+    * allwinner,sun8i-h3-de2-mixer0
+    * allwinner,sun8i-h3-de2-mixer1

Again, please explain why we need to have different compatibles
here. If it's only about the number of planes, this should be dealt
with a property, not a compatible.

Only mixer0 has "VEP" and write-back support, at least on H3.

What is that VEP? writeback support can also be expressed by a
property.

I don't know what VEP is...

VEP is probably Video Enhancement Processor (?). Although I'm not sure if that 
is really mixer specific. Icenowy, can you explain where did you get this info? 

Best regards,
Jernej

But we are really facing different cores, like sun50i-a64-mmc
and sun50i-a64-emmc.
