  1. ACT88xx regulators
  2. -------------------
  3. Required properties:
  4. - compatible: "active-semi,act8846" or "active-semi,act8865" or "active-semi,act8600"
  5. - reg: I2C slave address
  6. Optional properties:
  7. - system-power-controller: Telling whether or not this pmic is controlling
  8. the system power. See Documentation/devicetree/bindings/power/power-controller.txt .
  9. - active-semi,vsel-high: Indicates the VSEL pin is high.
  10. If this property is missing, assume the VSEL pin is low(0).
  11. Optional input supply properties:
  12. - for act8600:
  13. - vp1-supply: The input supply for DCDC_REG1
  14. - vp2-supply: The input supply for DCDC_REG2
  15. - vp3-supply: The input supply for DCDC_REG3
  16. - inl-supply: The input supply for LDO_REG5, LDO_REG6, LDO_REG7 and LDO_REG8
  17. SUDCDC_REG4, LDO_REG9 and LDO_REG10 do not have separate supplies.
  18. - for act8846:
  19. - vp1-supply: The input supply for REG1
  20. - vp2-supply: The input supply for REG2
  21. - vp3-supply: The input supply for REG3
  22. - vp4-supply: The input supply for REG4
  23. - inl1-supply: The input supply for REG5, REG6 and REG7
  24. - inl2-supply: The input supply for REG8 and LDO_REG9
  25. - inl3-supply: The input supply for REG10, REG11 and REG12
  26. - for act8865:
  27. - vp1-supply: The input supply for DCDC_REG1
  28. - vp2-supply: The input supply for DCDC_REG2
  29. - vp3-supply: The input supply for DCDC_REG3
  30. - inl45-supply: The input supply for LDO_REG1 and LDO_REG2
  31. - inl67-supply: The input supply for LDO_REG3 and LDO_REG4
  32. Any standard regulator properties can be used to configure the single regulator.
  33. The valid names for regulators are:
  34. - for act8846:
  35. REG1, REG2, REG3, REG4, REG5, REG6, REG7, REG8, REG9, REG10, REG11, REG12
  36. - for act8865:
  37. DCDC_REG1, DCDC_REG2, DCDC_REG3, LDO_REG1, LDO_REG2, LDO_REG3, LDO_REG4.
  38. - for act8600:
  39. DCDC_REG1, DCDC_REG2, DCDC_REG3, SUDCDC_REG4, LDO_REG5, LDO_REG6, LDO_REG7,
  40. LDO_REG8, LDO_REG9, LDO_REG10,
