* 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;
};
};
};
