1 STM32 VREFBUF - Voltage reference buffer
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.
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.
13 - vdda-supply: Phandle to the parent vdda supply regulator node.
