| 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>; |
| }; |
| ... |
| }; |
