+* TPS65086 Power Management Integrated Circuit (PMIC) bindings
+
+Required properties:
+ - compatible : Should be "ti,tps65086".
+ - reg : I2C slave address.
+ - interrupt-parent : Phandle to the parent interrupt controller.
+ - interrupts : The interrupt line the device is connected to.
+ - interrupt-controller : Marks the device node as an interrupt controller.
+ - #interrupt-cells : The number of cells to describe an IRQ, should be 2.
+ The first cell is the IRQ number.
+ The second cell is the flags, encoded as trigger
+ masks from ../interrupt-controller/interrupts.txt.
+ - 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.
+ - regulators: : List of child nodes that specify the regulator
+ initialization data. Child nodes must be named
+ after their hardware counterparts: buck[1-6],
+ ldoa[1-3], swa1, swb[1-2], and vtt. Each child
+ node is defined using the standard binding for
+ regulators and the optional regulator properties
+ defined below.
+
+Optional regulator properties:
+ - ti,regulator-step-size-25mv : This is applicable for buck[1,2,6], set this
+ if the regulator is factory set with a 25mv
+ step voltage mapping.
+ - ti,regulator-decay : This is applicable for buck[1-6], set this if
+ the output needs to decay, default is for
+ the output to slew down.
+
+Example:
+
+ pmic: tps65086@5e {
+ compatible = "ti,tps65086";
+ reg = <0x5e>;
+ interrupt-parent = <&gpio1>;
+ interrupts = <28 IRQ_TYPE_LEVEL_LOW>;
+ interrupt-controller;
+ #interrupt-cells = <2>;
+ gpio-controller;
+ #gpio-cells = <2>;
+
+ regulators {
+ buck1 {
+ regulator-name = "vcc1";
+ regulator-min-microvolt = <1600000>;
+ regulator-max-microvolt = <1600000>;
+ regulator-boot-on;
+ ti,regulator-decay;
+ ti,regulator-step-size-25mv;
+ };
+ };
+ };
