My bot found errors running 'make dt_binding_check' on your patch:

/builds/robherring/linux-dt-review/Documentation/devicetree/bindings/leds/leds-mt6360.example.dt.yaml: led-controller: led@0:color:0:0: 9 is greater than the maximum of 8
	From schema: /builds/robherring/linux-dt-review/Documentation/devicetree/bindings/leds/leds-mt6360.yaml


See https://patchwork.ozlabs.org/patch/1377747

If you already ran 'make dt_binding_check' and didn't see the above
error(s), then make sure dt-schema is up to date:

pip3 install git+https://github.com/devicetree-org/dt-schema.git@master --upgrade

Please check and re-submit.

This should be multi-led node. See [0] for a reference.

Maybe add LED_FUNCTION_MOONLIGHT ?
