+All voltage regulators are defined as subnodes of the regulators node. A list
+of regulators provided by this controller are defined as subnodes of the
+PMIC's node. Each regulator 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_vpa
+LDO:
+ ldo_vtcxo, ldo_vcn28, ldo_vcn33_bt, ldo_vcn33_wifi, ldo_va, ldo_vcama,
