+  This module is part of the Marvell 88PM88X MFD device. For more details
+  see Documentation/devicetree/bindings/mfd/marvell,88pm88x.yaml.
+
+  The regulator controller is represented as a sub-node of the PMIC node
+  in the device tree.
+
+  The valid names for 88PM886 regulator nodes are ldo[1-9], ldo1[0-6], buck[1-5].
