  1. Fixed Voltage regulators
  2. Required properties:
  3. - compatible: Must be "regulator-fixed";
  4. Optional properties:
  5. - gpio: gpio to use for enable control
  6. - startup-delay-us: startup time in microseconds
  7. - enable-active-high: Polarity of GPIO is Active high
  8. If this property is missing, the default assumed is Active low.
  9. - gpio-open-drain: GPIO is open drain type.
  10. If this property is missing then default assumption is false.
  11. Any property defined as part of the core regulator
  12. binding, defined in regulator.txt, can also be used.
  13. However a fixed voltage regulator is expected to have the
  14. regulator-min-microvolt and regulator-max-microvolt
  15. to be the same.
  16. Example:
  17. abc: fixedregulator@0 {
  18. compatible = "regulator-fixed";
  19. regulator-name = "fixed-supply";
  20. regulator-min-microvolt = <1800000>;
  21. regulator-max-microvolt = <1800000>;
  22. gpio = <&gpio1 16 0>;
  23. startup-delay-us = <70000>;
  24. enable-active-high;
  25. regulator-boot-on;
  26. gpio-open-drain;
  27. };
