1Spreadtrum SC2731 Voltage regulators
2
3The SC2731 integrates low-voltage and low quiescent current DCDC/LDO.
414 LDO and 3 DCDCs are designed for external use. All DCDCs/LDOs have
5their own bypass (power-down) control signals. External tantalum or MLCC
6ceramic capacitors are recommended to use with these LDOs.

8Required properties:
9 - compatible: should be "sprd,sc27xx-regulator".

11List of regulators provided by this controller. It is named according to
12its regulator type, BUCK_<name> and LDO_<name>. The definition for each
13of these nodes is defined using the standard binding for regulators at
14Documentation/devicetree/bindings/regulator/regulator.txt.
15
16The valid names for regulators are:
17BUCK:
18	BUCK_CPU0, BUCK_CPU1, BUCK_RF
19LDO:
20	LDO_CAMA0, LDO_CAMA1, LDO_CAMMOT, LDO_VLDO, LDO_EMMCCORE, LDO_SDCORE,
21	LDO_SDIO, LDO_WIFIPA, LDO_USB33, LDO_CAMD0, LDO_CAMD1, LDO_CON,
22	LDO_CAMIO, LDO_SRAM
23
24Example:
25	regulators {
26		compatible = "sprd,sc27xx-regulator";
27
28		vddarm0: BUCK_CPU0 {
29			regulator-name = "vddarm0";
30			regulator-min-microvolt = <400000>;
31			regulator-max-microvolt = <1996875>;
32			regulator-ramp-delay = <25000>;
33			regulator-always-on;
34		};
35
36		vddcama0: LDO_CAMA0 {
37			regulator-name = "vddcama0";
38			regulator-min-microvolt = <1200000>;
39			regulator-max-microvolt = <3750000>;
40			regulator-enable-ramp-delay = <100>;
