* TPS65912 Power Management Integrated Circuit bindings
Required properties:
- compatible : Should be "ti,tps65912".
- reg : Slave address or chip select number (I2C / SPI).
- interrupt-parent : 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: dcdc[1-4] and
ldo[1-10]. Each child nodes is defined using the
standard binding for regulators.
Example:
pmic: tps65912@2d {
compatible = "ti,tps65912";
reg = <0x2d>;
interrupt-parent = <&gpio1>;
interrupts = <28 IRQ_TYPE_LEVEL_LOW>;
interrupt-controller;
#interrupt-cells = <2>;
gpio-controller;
#gpio-cells = <2>;
regulators {
dcdc1 {
regulator-name = "vdd_core";
regulator-min-microvolt = <912000>;
regulator-max-microvolt = <1144000>;
regulator-boot-on;
regulator-always-on;
};
ldo1 {
regulator-name = "ldo1";
regulator-min-microvolt = <1900000>;
regulator-max-microvolt = <1900000>;
};
};
};
