It's by default. Drop.

It does not look like you tested the DTS against bindings. Please run
`make dtbs_check` (see
Documentation/devicetree/bindings/writing-schema.rst for instructions).

Node names should be generic. See also explanation and list of examples
in DT specification:
https://devicetree-specification.readthedocs.io/en/latest/chapter2-devicetree-basics.html#generic-names-recommendation
Ok.
quoted

+			#address-cells = <1>;
+			#size-cells = <1>;
+			ranges;

reg is always after compatible. Ranges is third. Then you will spot that
address is wrong.
Ok.

Fix alignment.
Ok.
