+Mediatek MT6359 Regulator
+
+Required properties:
+- compatible: "mediatek,mt6359-regulator"
+- mt6359regulator: 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_vs1, buck_vgpu11, buck_vmodem, buck_vpu, buck_vcore, buck_vs2,
+  buck_vpa, buck_vproc2, buck_vproc1, buck_vcore_sshub
+LDO:
+  ldo_vaud18, ldo_vsim1, ldo_vibr, ldo_vrf12, ldo_vusb, ldo_vsram_proc2,
+  ldo_vio18, ldo_vcamio, ldo_vcn18, ldo_vfe28, ldo_vcn13, ldo_vcn33_1_bt,
+  ldo_vcn13_1_wifi, ldo_vaux18, ldo_vsram_others, ldo_vefuse, ldo_vxo22,
+  ldo_vrfck, ldo_vbif28, ldo_vio28, ldo_vemc, ldo_vcn33_2_bt, ldo_vcn33_2_wifi,
+  ldo_va12, ldo_va09, ldo_vrf18, ldo_vsram_md, ldo_vufs, ldo_vm18, ldo_vbbck,

+Example:
+	pmic {
+		compatible = "mediatek,mt6359";
+
+		mt6359regulator: mt6359regulator {
+			compatible = "mediatek,mt6359-regulator";
