   1 Spreadtrum SC2731 Voltage regulators
   2
   3 The SC2731 integrates low-voltage and low quiescent current DCDC/LDO.
   4 14 LDO and 3 DCDCs are designed for external use. All DCDCs/LDOs have
   5 their own bypass (power-down) control signals. External tantalum or MLCC
   6 ceramic capacitors are recommended to use with these LDOs.

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

  11 List of regulators provided by this controller. It is named according to
  12 its regulator type, BUCK_<name> and LDO_<name>. The definition for each
  13 of these nodes is defined using the standard binding for regulators at
  14 Documentation/devicetree/bindings/regulator/regulator.txt.
  15
  16 The valid names for regulators are:
  17 BUCK:
  18         BUCK_CPU0, BUCK_CPU1, BUCK_RF
  19 LDO:
  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
