-* TPS65086 Power Management Integrated Circuit (PMIC) bindings
-
-Required properties:
- - compatible		: Should be "ti,tps65086".
- - reg			: I2C slave address.
- - 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[1-6], 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;
-			};
-		};
