@ -8,6 +8,8 @@ Optional properties:
- startup-delay-us: startup time in microseconds
- enable-active-high: Polarity of GPIO is Active high
If this property is missing, the default assumed is Active low.
- gpio-open-drain: GPIO is open drain type.
If this property is missing then default assumption is false.
Any property defined as part of the core regulator
binding, defined in regulator.txt, can also be used.

TPS6586x family of regulators
Required properties:
- compatible: "ti,tps6586x"
- reg: I2C slave address
- interrupts: the interrupt outputs of the controller
- #gpio-cells: number of cells to describe a GPIO
- gpio-controller: mark the device as a GPIO controller
- regulators: list of regulators provided by this controller, must be named
after their hardware counterparts: sm[0-2], ldo[0-9] and ldo_rtc
Each regulator is defined using the standard binding for regulators.
Example:
pmu: tps6586x@34 {
compatible = "ti,tps6586x";
reg = <0x34>;
interrupts = <0 88 0x4>;
#gpio-cells = <2>;
