  1. Device-Tree bindings for regulators of Active-semi ACT8945A Multi-Function Device
    2. 

  2. 

  3. Required properties:
    4. 

  4.  - compatible: "active-semi,act8945a", please refer to ../mfd/act8945a.txt.
    5. 

  5. 

  6. Optional properties:
    7. 

  7. - active-semi,vsel-high: Indicates if the VSEL pin is set to logic-high.
    8. 

  8.   If this property is missing, assume the VSEL pin is set to logic-low.
    9. 

  9. 

  10. Optional input supply properties:
    11. 

  11.   - vp1-supply: The input supply for REG_DCDC1
    12. 

  12.   - vp2-supply: The input supply for REG_DCDC2
    13. 

  13.   - vp3-supply: The input supply for REG_DCDC3
    14. 

  14.   - inl45-supply: The input supply for REG_LDO1 and REG_LDO2
    15. 

  15.   - inl67-supply: The input supply for REG_LDO3 and REG_LDO4
    16. 

  16. 

  17. Any standard regulator properties can be used to configure the single regulator.
    18. 

  18. 

  19. The valid names for regulators are:
    20. 

  20. 	REG_DCDC1, REG_DCDC2, REG_DCDC3, REG_LDO1, REG_LDO2, REG_LDO3, REG_LDO4.
    21.
