TPS65218 family of regulators
Required properties:
For tps65218 regulators/LDOs
- compatible:
- "ti,tps65218-dcdc1" for DCDC1
- "ti,tps65218-dcdc2" for DCDC2
- "ti,tps65218-dcdc3" for DCDC3
- "ti,tps65218-dcdc4" for DCDC4
- "ti,tps65218-dcdc5" for DCDC5
- "ti,tps65218-dcdc6" for DCDC6
- "ti,tps65218-ldo1" for LDO1
- compatible: "ti,tps65218"
- reg: I2C slave address
Optional properties:
- Any optional property defined in bindings/regulator/regulator.txt
- List of regulators provided by this controller, must be named
after their hardware counterparts: dcdc[1-6] and ldo1
- This is the list of child nodes that specify the regulator
initialization data for defined regulators. Not all regulators for the given
device need to be present. The definition for each of these nodes is defined
using the standard binding for regulators found at ./regulator.txt.
The valid names for regulators are:
tps65217: regulator-dcdc1, regulator-dcdc2, regulator-dcdc3, regulator-dcdc4,
regulator-dcdc5, regulator-dcdc6, regulator-ldo1, regulator-ls3.
Each regulator is defined using the standard binding for regulators.
Example:
tps65218: tps65218@24 {
reg = <0x24>;
compatible = "ti,tps65218";
interrupts = <GIC_SPI 7 IRQ_TYPE_NONE>; /* NMIn */
interrupt-controller;
#interrupt-cells = <2>;
xyz: regulator@0 {
compatible = "ti,tps65218-dcdc1";
regulator-min-microvolt = <1000000>;
regulator-max-microvolt = <3000000>;
dcdc1: regulator-dcdc1 {
regulator-name = "vdd_core";
regulator-min-microvolt = <912000>;
regulator-max-microvolt = <1144000>;
regulator-boot-on;
regulator-always-on;
};
dcdc2: regulator-dcdc2 {
regulator-name = "vdd_mpu";
regulator-min-microvolt = <912000>;
regulator-max-microvolt = <1378000>;
regulator-boot-on;
regulator-always-on;
};
dcdc3: regulator-dcdc3 {
regulator-name = "vdcdc3";
regulator-min-microvolt = <1500000>;

regulator-max-microvolt = <1000000>;
regulator-boot-on;
regulator-always-on;
};
dcdc6: regulator-dcdc6 {
regulator-name = "v1_8bat";
regulator-min-microvolt = <1800000>;
regulator-max-microvolt = <1800000>;
regulator-boot-on;
regulator-always-on;
};
ldo1: regulator-ldo1 {
regulator-min-microvolt = <1800000>;
regulator-max-microvolt = <1800000>;
regulator-boot-on;
regulator-always-on;
};
ls3: regulator-ls3 {
regulator-min-microvolt = <100000>;

};
