-Spreadtrum SC2731 Voltage regulators
-
-The SC2731 integrates low-voltage and low quiescent current DCDC/LDO.
-14 LDO and 3 DCDCs are designed for external use. All DCDCs/LDOs have
-their own bypass (power-down) control signals. External tantalum or MLCC
-ceramic capacitors are recommended to use with these LDOs.
-
-Required properties:
- - compatible: should be "sprd,sc27xx-regulator".
-
-List of regulators provided by this controller. It is named according to
-its regulator type, BUCK_<name> and LDO_<name>. The definition for each
-of these nodes is defined using the standard binding for regulators at
-Documentation/devicetree/bindings/regulator/regulator.txt.
-
-The valid names for regulators are:
-BUCK:
-	BUCK_CPU0, BUCK_CPU1, BUCK_RF
-LDO:
-	LDO_CAMA0, LDO_CAMA1, LDO_CAMMOT, LDO_VLDO, LDO_EMMCCORE, LDO_SDCORE,
-	LDO_SDIO, LDO_WIFIPA, LDO_USB33, LDO_CAMD0, LDO_CAMD1, LDO_CON,
-	LDO_CAMIO, LDO_SRAM
-
-Example:
-	regulators {
-		compatible = "sprd,sc27xx-regulator";
-
-		vddarm0: BUCK_CPU0 {
-			regulator-name = "vddarm0";
-			regulator-min-microvolt = <400000>;
-			regulator-max-microvolt = <1996875>;
-			regulator-ramp-delay = <25000>;
-			regulator-always-on;
-		};
-
-		vddcama0: LDO_CAMA0 {
-			regulator-name = "vddcama0";
-			regulator-min-microvolt = <1200000>;
-			regulator-max-microvolt = <3750000>;
-			regulator-enable-ramp-delay = <100>;
-		};
-		...
-	};
