One thing I've noticed now is that the dt schema currently explicitly
disallows orientation-gpios for anything that's not sm8450, sm8550 or
x1e80100.

  arch/arm64/boot/dts/qcom/qcm6490-fairphone-fp5.dtb: pmic-glink: orientation-gpios: False schema does not allow [[84, 140, 0]]
          from schema $id: http://devicetree.org/schemas/soc/qcom/qcom,pmic-glink.yaml#

So I'd think also this series will cause some extra validation errors if
the schema is not adjusted? Are you planning to do that?
