+TI LP87561 PMIC:
+
+This is a single output 4-phase regulator configuration
+
+Required properties:
+  - compatible:        "ti,lp87561-q1"
+  - reg:               I2C slave address.
+  - gpio-controller:   Marks the device node as a GPIO Controller.
+  - #gpio-cells:       Should be two.  The first cell is the pin number and
+                       the second cell is used to specify flags.
+                       See ../gpio/gpio.txt for more information.
+  - xxx-in-supply:     Phandle to parent supply node of each regulator
+                       populated under regulators node. xxx should match
+                       the supply_name populated in driver.
+Example:
+
+lp87561_pmic: pmic@62 {
+       compatible = "ti,lp87561-q1";
+       reg = <0x62>;
+       gpio-controller;
+       #gpio-cells = <2>;
+
+       buck3210-in-supply = <&vsys_3v3>;
+
+       regulators: regulators {
+               buck3210_reg: buck3210 {
+                       /* VDD_CORE */
+                       regulator-name = "buck3210";
+                       regulator-min-microvolt = <800000>;
+                       regulator-max-microvolt = <800000>;
+                       regulator-always-on;
+                       regulator-boot-on;
+               };
+       };
+};
