1 STM32 VREFBUF - Voltage reference buffer
2
3 Some STM32 devices embed a voltage reference buffer which can be used as
4 voltage reference for ADCs, DACs and also as voltage reference for external
5 components through the dedicated VREF+ pin.

7 Required properties:
8 - compatible:           Must be "st,stm32-vrefbuf".
9 - reg:                  Offset and length of VREFBUF register set.
10 - clocks:               Must contain an entry for peripheral clock.
