* 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;
|
