-Binding for Maxim MAX77686 regulators
-
-This is a part of the device tree bindings of MAX77686 multi-function device.
-More information can be found in ../mfd/max77686.txt file.
-
-The MAX77686 PMIC has 9 high-efficiency Buck and 26 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:
-- voltage-regulators : The regulators of max77686 have to be instantiated
-  under subnode named "voltage-regulators" using the following format.
-
-	regulator_name {
-		regulator-compatible = LDOn/BUCKn
-		standard regulator constraints....
-	};
-	refer Documentation/devicetree/bindings/regulator/regulator.txt
-
-  The regulator node's name should be initialized with a string
-to get matched with their hardware counterparts as follow:
-
-	-LDOn 	:	for LDOs, where n can lie in range 1 to 26.
-			example: LDO1, LDO2, LDO26.
-	-BUCKn 	:	for BUCKs, where n can lie in range 1 to 9.
-			example: BUCK1, BUCK5, BUCK9.
-
-  Regulators which can be turned off during system suspend:
-	-LDOn	:	2, 6-8, 10-12, 14-16,
-	-BUCKn	:	1-4.
-  Use standard regulator bindings for it ('regulator-off-in-suspend').
-
-  LDO20, LDO21, LDO22, BUCK8 and BUCK9 can be configured to GPIO enable
-  control. To turn this feature on this property must be added to the regulator
-  sub-node:
-	- maxim,ena-gpios :	one GPIO specifier enable control (the gpio
-				flags are actually ignored and always
-				ACTIVE_HIGH is used)
-
-Example:
-
-	max77686: pmic@9 {
-		compatible = "maxim,max77686";
-		interrupt-parent = <&wakeup_eint>;
-		interrupts = <26 IRQ_TYPE_LEVEL_LOW>;
-		reg = <0x09>;
-
-		voltage-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;
-			};
-
-			buck9_reg: BUCK9 {
-				regulator-name = "CAM_ISP_CORE_1.2V";
-				regulator-min-microvolt = <1000000>;
-				regulator-max-microvolt = <1200000>;
-				maxim,ena-gpios = <&gpm0 3 GPIO_ACTIVE_HIGH>;
-			};
-	};
