We put the peripheral nodes in address order, so this one should go
prior to the IPU node.

+ compatible = "amd,imageon-200.1", "amd,imageon";

I can't find the dt-bindings for these compatible entries. Have you
documented them?


It is the same as qcom,adreno which is documented here:

Documentation/devicetree/bindings/display/msm/gpu.txt

I guess I should add amd,imageon there.

You could drop this @0
