  1. STM32 VREFBUF - Voltage reference buffer
  2. Some STM32 devices embed a voltage reference buffer which can be used as
  3. voltage reference for ADCs, DACs and also as voltage reference for external
  4. components through the dedicated VREF+ pin.
  5. Required properties:
  6. - compatible: Must be "st,stm32-vrefbuf".
  7. - reg: Offset and length of VREFBUF register set.
  8. - clocks: Must contain an entry for peripheral clock.
  9. Optional properties:
  10. - vdda-supply: Phandle to the parent vdda supply regulator node.
  11. Example:
  12. vrefbuf: regulator@58003c00 {
  13. compatible = "st,stm32-vrefbuf";
  14. reg = <0x58003C00 0x8>;
  15. clocks = <&rcc VREF_CK>;
  16. regulator-min-microvolt = <1500000>;
  17. regulator-max-microvolt = <2500000>;
  18. vdda-supply = <&vdda>;
  19. };
