Please use subject lines matching the style for the subsystem.  This
makes it easier for people to identify relevant patches.  The binding
itself looks good, just the subject for the patch.

+* 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>;
+			};
