  1. Binding for Maxim MAX77802 regulators
  2. This is a part of device tree bindings of MAX77802 multi-function device.
  3. More information can be found in bindings/mfd/max77802.txt file.
  4. The MAX77802 PMIC has 10 high-efficiency Buck and 32 Low-dropout (LDO)
  5. regulators that can be controlled over I2C.
  6. Following properties should be present in main device node of the MFD chip.
  7. Optional node:
  8. - regulators : The regulators of max77802 have to be instantiated
  9. under subnode named "regulators" using the following format.
  10. regulator-name {
  11. standard regulator constraints....
  12. };
  13. refer Documentation/devicetree/bindings/regulator/regulator.txt
  14. The regulator node name should be initialized with a string to get matched
  15. with their hardware counterparts as follow. The valid names are:
  16. -LDOn : for LDOs, where n can lie in ranges 1-15, 17-21, 23-30
  17. and 32-35.
  18. example: LDO1, LDO2, LDO35.
  19. -BUCKn : for BUCKs, where n can lie in range 1 to 10.
  20. example: BUCK1, BUCK5, BUCK10.
  21. Example:
  22. max77802@09 {
  23. compatible = "maxim,max77802";
  24. interrupt-parent = <&wakeup_eint>;
  25. interrupts = <26 0>;
  26. reg = <0x09>;
  27. #address-cells = <1>;
  28. #size-cells = <0>;
  29. regulators {
  30. ldo11_reg: LDO11 {
  31. regulator-name = "vdd_ldo11";
  32. regulator-min-microvolt = <1900000>;
  33. regulator-max-microvolt = <1900000>;
  34. regulator-always-on;
  35. };
  36. buck1_reg: BUCK1 {
  37. regulator-name = "vdd_mif";
  38. regulator-min-microvolt = <950000>;
  39. regulator-max-microvolt = <1300000>;
  40. regulator-always-on;
  41. regulator-boot-on;
  42. };
  43. };
