+Device-Tree bindings for regulators of Active-semi ACT8945A Multi-Function Device
+
+Required properties:
+ - compatible: "active-semi,act8945a-regulator"
+
+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 DCDC_REG1
+ - vp2-supply: The input supply for DCDC_REG2
+ - vp3-supply: The input supply for DCDC_REG3
+ - inl45-supply: The input supply for LDO_REG1 and LDO_REG2
+ - inl67-supply: The input supply for LDO_REG3 and LDO_REG4
+
+Any standard regulator properties can be used to configure the single regulator.
+
+The valid names for regulators are:
+ DCDC_REG1, DCDC_REG2, DCDC_REG3, LDO_REG1, LDO_REG2, LDO_REG3, LDO_REG4.
+
+Example:
+
+ pmic {
+ compatible = "active-semi,act8945a-regulator";
+ active-semi,vsel-high;
+
+ regulators {
+ vdd_1v35_reg: DCDC_REG1 {
+ regulator-name = "VDD_1V35";
+ regulator-min-microvolt = <1350000>;
+ regulator-max-microvolt = <1350000>;
+ regulator-always-on;
+ };
+
+ vdd_1v2_reg: DCDC_REG2 {
+ regulator-name = "VDD_1V2";
+ regulator-min-microvolt = <1100000>;
+ regulator-max-microvolt = <1300000>;
+ regulator-always-on;
+ };
+
+ vdd_3v3_reg: DCDC_REG3 {
+ regulator-name = "VDD_3V3";
+ regulator-min-microvolt = <3300000>;
+ regulator-max-microvolt = <3300000>;
+ regulator-always-on;
+ };
+
+ vdd_fuse_reg: LDO_REG1 {
+ regulator-name = "VDD_FUSE";
+ regulator-min-microvolt = <2500000>;
+ regulator-max-microvolt = <2500000>;
+ regulator-always-on;
+ };
+
+ vdd_3v3_lp_reg: LDO_REG2 {
+ regulator-name = "VDD_3V3_LP";
+ regulator-min-microvolt = <3300000>;
+ regulator-max-microvolt = <3300000>;
+ regulator-always-on;
+ };
+
+ vdd_led_reg: LDO_REG3 {
+ regulator-name = "VDD_LED";
+ regulator-min-microvolt = <3300000>;
+ regulator-max-microvolt = <3300000>;
+ regulator-always-on;
+ };
+
+ vdd_sdhc_1v8_reg: LDO_REG4 {
+ regulator-name = "VDD_SDHC_1V8";
+ regulator-min-microvolt = <1800000>;
+ regulator-max-microvolt = <1800000>;
+ regulator-always-on;
+ };
+ };
+ };
