Hi Dmitry,

IIRC issues with the x1e80100 dp-controller bindings (i.e. the reg 
bindings) weren't being picked up by dtschema because the x1e80100-dp 
compatible string wasn't in dp-controller.yaml.

I can add this to the commit msg after moving the 
assigned-clocks/clock-parents change to patch 3.

Would it be better if I kept the compatible/reg bindings fix in this 
commit then squashed the assigned-clocks/clock-parents change with patch 3?

Thanks,
