+Binding for Maxim MAX77802 regulators
+
+This is a part of device tree bindings of MAX77802 multi-function device.
+More information can be found in bindings/mfd/max77802.txt file.
+
+The MAX77802 PMIC has 10 high-efficiency Buck and 32 Low-dropout (LDO)
+regulators that can be controlled over I2C.
+
+Following properties should be present in main device node of the MFD chip.
+
+Optional node:
+- regulators : The regulators of max77802 have to be instantiated
+  under subnode named "regulators" using the following format.
+
+	regulator-name {
+		standard regulator constraints....
+	};
+	refer Documentation/devicetree/bindings/regulator/regulator.txt
+
+The regulator node name should be initialized with a string to get matched
+with their hardware counterparts as follow. The valid names are:
+
+	-LDOn 	:	for LDOs, where n can lie in ranges 1-15, 17-21, 23-30
+			and 32-35.
+			example: LDO1, LDO2, LDO35.
+	-BUCKn 	:	for BUCKs, where n can lie in range 1 to 10.
+			example: BUCK1, BUCK5, BUCK10.
+Example:
+
+	max77802@09 {
+		compatible = "maxim,max77802";
+		interrupt-parent = <&wakeup_eint>;
+		interrupts = <26 0>;
+		reg = <0x09>;
+		#address-cells = <1>;
+		#size-cells = <0>;
+
+		regulators {
+			ldo11_reg: LDO11 {
+				regulator-name = "vdd_ldo11";
+				regulator-min-microvolt = <1900000>;
+				regulator-max-microvolt = <1900000>;
+				regulator-always-on;
+			};
+
+			buck1_reg: BUCK1 {
+				regulator-name = "vdd_mif";
+				regulator-min-microvolt = <950000>;
+				regulator-max-microvolt = <1300000>;
+				regulator-always-on;
+				regulator-boot-on;
+			};
+	};
