+* Dialog Semiconductor SLG51000 Voltage Regulator
+
+Required properties:
+- compatible : Should be "dlg,slg51000" for SLG51000
+- reg : Specifies the I2C slave address.
+- xxx-supply: Input voltage supply regulator for ldo3 to ldo7.
+ These entries are required if regulators are enabled for a device.
+ An absence of these properties can cause the regulator registration to fail.
+ If some of input supply is powered through battery or always-on supply then
+ also it is required to have these parameters with proper node handle of always
+ on power supply.
+ vin3-supply: Input supply for ldo3
+ vin4-supply: Input supply for ldo4
+ vin5-supply: Input supply for ldo5
+ vin6-supply: Input supply for ldo6
+ vin7-supply: Input supply for ldo7
+
+Optional properties:
+- interrupt-parent : Specifies the reference to the interrupt controller.
+- interrupts : IRQ line information.
+- dlg,cs-gpios : Specify a valid GPIO for chip select
+
+Sub-nodes:
+- regulators : This node defines the settings for the regulators.
+ The content of the sub-node is defined by the standard binding
+ for regulators; see regulator.txt.
+
+ The SLG51000 regulators are bound using their names listed below:
+ ldo1
+ ldo2
+ ldo3
+ ldo4
+ ldo5
+ ldo6
+ ldo7
+
+Optional properties for regulators:
+- enable-gpios : Specify a valid GPIO for platform control of the regulator.
+
+Example:
+ pmic: slg51000@75 {
+ compatible = "dlg,slg51000";
+ reg = <0x75>;
+
+ regulators {
+ ldo1 {
+ regulator-name = "ldo1";
+ regulator-min-microvolt = <2400000>;
+ regulator-max-microvolt = <3300000>;
+ };
+
+ ldo2 {
+ regulator-name = "ldo2";
+ regulator-min-microvolt = <2400000>;
+ regulator-max-microvolt = <3300000>;
+ };
+
+ ldo3 {
+ regulator-name = "ldo3";
+ regulator-min-microvolt = <1200000>;
+ regulator-max-microvolt = <3750000>;
+ };
+
+ ldo4 {
+ regulator-name = "ldo4";
+ regulator-min-microvolt = <1200000>;
+ regulator-max-microvolt = <3750000>;
+ };
+
+ ldo5 {
+ regulator-name = "ldo5";
+ regulator-min-microvolt = <500000>;
+ regulator-max-microvolt = <1200000>;
+ };
+
+ ldo6 {
+ regulator-name = "ldo6";
+ regulator-min-microvolt = <500000>;
+ regulator-max-microvolt = <1200000>;
+ };
+
+ ldo7 {
+ regulator-name = "ldo7";
+ regulator-min-microvolt = <1200000>;
+ regulator-max-microvolt = <3750000>;
+ };
+ };
+ };
