Device-Tree bindings for regulators of Active-semi ACT8945A Multi-Function Device



Required properties:

 - compatible: "active-semi,act8945a", please refer to ../mfd/act8945a.txt.



Optional properties:

- active-semi,vsel-high: Indicates if the VSEL pin is set to logic-high.

  If this property is missing, assume the VSEL pin is set to logic-low.



Optional input supply properties:

  - vp1-supply: The input supply for REG_DCDC1

  - vp2-supply: The input supply for REG_DCDC2

  - vp3-supply: The input supply for REG_DCDC3

  - inl45-supply: The input supply for REG_LDO1 and REG_LDO2

  - inl67-supply: The input supply for REG_LDO3 and REG_LDO4



Any standard regulator properties can be used to configure the single regulator.



The valid names for regulators are:

	REG_DCDC1, REG_DCDC2, REG_DCDC3, REG_LDO1, REG_LDO2, REG_LDO3, REG_LDO4.



Example:

	pmic@5b {

		compatible = "active-semi,act8945a";

		reg = <0x5b>;

		status = "okay";



		active-semi,vsel-high;



		regulators {

			vdd_1v35_reg: REG_DCDC1 {

				regulator-name = "VDD_1V35";

				regulator-min-microvolt = <1350000>;

				regulator-max-microvolt = <1350000>;

				regulator-always-on;

			};



			vdd_1v2_reg: REG_DCDC2 {

				regulator-name = "VDD_1V2";

				regulator-min-microvolt = <1100000>;

				regulator-max-microvolt = <1300000>;

				regulator-always-on;

			};



			vdd_3v3_reg: REG_DCDC3 {

				regulator-name = "VDD_3V3";

				regulator-min-microvolt = <3300000>;

				regulator-max-microvolt = <3300000>;

				regulator-always-on;

			};



			vdd_fuse_reg: REG_LDO1 {

				regulator-name = "VDD_FUSE";

				regulator-min-microvolt = <2500000>;

				regulator-max-microvolt = <2500000>;

				regulator-always-on;

			};



			vdd_3v3_lp_reg: REG_LDO2 {

				regulator-name = "VDD_3V3_LP";

				regulator-min-microvolt = <3300000>;

				regulator-max-microvolt = <3300000>;

				regulator-always-on;

			};



			vdd_led_reg: REG_LDO3 {

				regulator-name = "VDD_LED";

				regulator-min-microvolt = <3300000>;

				regulator-max-microvolt = <3300000>;

				regulator-always-on;

			};



			vdd_sdhc_1v8_reg: REG_LDO4 {

				regulator-name = "VDD_SDHC_1V8";

				regulator-min-microvolt = <1800000>;

				regulator-max-microvolt = <1800000>;

				regulator-always-on;

			};

		};
