+Device-Tree bindings for regulators of Active-semi ACT8945A Multi-Function Device
+
+Required properties:
+ - compatible: "active-semi,act8945a", please refer to ../mfd/act8945a.txt.
+
+Optional properties:
+- active-semi,vsel-high: Indicates if the VSEL pin is set to logic-high.
+  If this property is missing, assume the VSEL pin is set to logic-low.
+
+Optional input supply properties:
+  - vp1-supply: The input supply for REG_DCDC1
+  - vp2-supply: The input supply for REG_DCDC2
+  - vp3-supply: The input supply for REG_DCDC3
+  - inl45-supply: The input supply for REG_LDO1 and REG_LDO2
+  - inl67-supply: The input supply for REG_LDO3 and REG_LDO4
+
+Any standard regulator properties can be used to configure the single regulator.
+regulator-initial-mode, regulator-allowed-modes and regulator-mode could be
+specified using mode values from dt-bindings/regulator/active-semi,8945a-regulator.h
+file.
+
+The valid names for regulators are:
+	REG_DCDC1, REG_DCDC2, REG_DCDC3, REG_LDO1, REG_LDO2, REG_LDO3, REG_LDO4.
+
+Example:
+
+#include <dt-bindings/regulator/active-semi,8945a-regulator.h>
+
