Some STM32 devices embed a voltage reference buffer which can be used as
voltage reference for ADCs, DACs and also as voltage reference
for external components through the dedicated VREF+ pin.

This patchset adds vrefbuf regulator driver, device tree bindings and
vrefbuf device tree node for STM32H7 SoC.

Fabrice Gasnier (3):
  dt-bindings: regulator: Add STM32 Voltage Reference Buffer
  regulator: Add support for stm32-vrefbuf
  ARM: dts: stm32: add vrefbuf to stm32h743
