    +Mediatek MT6392 Regulator
    +
    +Required properties:
    +- compatible: "mediatek,mt6392-regulator"
    +- mt6392regulator: List of regulators provided by this controller. It is named
    + according to its regulator type, buck_<name> and ldo_<name>.
    + The definition for each of these nodes is defined using the standard binding
    + for regulators at Documentation/devicetree/bindings/regulator/regulator.txt.
    +
    +The valid names for regulators are::
    +BUCK:
    + buck_vproc, buck_vsys, buck_vcore
    +LDO:
    + ldo_vxo22, ldo_vaud22, ldo_vcama, ldo_vaud28, ldo_vadc18, ldo_vcn35,
    + ldo_vio28. ldo_vusb, ldo_vmc, ldo_vmch, ldo_vemc3v3, ldo_vgp1, ldo_vgp2,
    + ldo_vcn18, ldo_vcamaf, ldo_vm, ldo_vio18, ldo_vcamd, ldo_vcamio, ldo_vm25,
