Did you disable it anywhere?

Node names should be generic. See also an explanation and list of
examples (not exhaustive) in DT specification:
https://devicetree-specification.readthedocs.io/en/latest/chapter2-devicetree-basics.html#generic-names-recommendation
If you cannot find a name matching your device, please check in kernel
sources for similar cases or you can grow the spec (via pull request to
DT spec repo).

e.g. pmic

+		compatible = "mediatek,mt6315-regulator";
+		reg = <0x6 0 0xb>;
