-- Any optional property defined in bindings/regulator/regulator.txt
+- compatible: "ti,tps65218"
+- reg: I2C slave address
+- 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
+ Documentation/devicetree/bindings/regulator/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>;
+
+ 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 = <1500000>;
+ regulator-boot-on;
+ regulator-always-on;
