+Mediatek MT6358 Regulator
+
+Required properties:
+- compatible: "mediatek,mt6358-regulator"
+- mt6358regulator: 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_vdram1, buck_vcore, buck_vpa, buck_vproc11, buck_vproc12, buck_vgpu,
+ buck_vs2, buck_vmodem, buck_vs1
+LDO:
+ ldo_vdram2, ldo_vsim1, ldo_vibr, ldo_vrf12, ldo_vio18, ldo_vusb, ldo_vcamio,
+ ldo_vcamd, ldo_vcn18, ldo_vfe28, ldo_vsram_proc11, ldo_vcn28, ldo_vsram_others,
+ ldo_vsram_gpu, ldo_vxo22, ldo_vefuse, ldo_vaux18, ldo_vmch, ldo_vbif28,
+ ldo_vsram_proc12, ldo_vcama1, ldo_vemc, ldo_vio28, ldo_va12, ldo_vrf18,
