-* 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
