+description:
+  The MediaTek MT6311 is an I2C power management IC that provides one step-down
+  converter and one low-dropout regulator. The regulators are named VDVFS and
+  VBIASN, respectively.

-Required properties:
-- compatible: "mediatek,mt6311-regulator"
-- reg: I2C slave address, usually 0x6b.
-- regulators: List of regulators provided by this controller. It is named
-  to VDVFS and VBIASN.
-  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:
-  VDVFS
-LDO:
-  VBIASN
