+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,
+ ldo_vefuse
