Hi Dmitry,

Ack.

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,

Just explain, _why_ you are performing the change, not what is being
done (this can be understood from the patch itself).

That depends. If these chunks are required to fix warnings / errors
after adding compat string, then keep them in this patch. If not, split
them to other patches.

That's not a correct tag really - drop the quotes. If this was added by
b4, I think you might be using an older version.

Hi Krzysztof,

Thanks for the catch -- I'll upgrade b4.
