Subject: [PATCH v2 0/4] regulator: add support for the STM32 ADC booster

Add support for the 3.3V booster regulator embedded in stm32h7 and stm32mp1
devices, that can be used to supply ADC analog input switches.
It's useful to reach full ADC performance when their supply is below 2.7V
(vdda by default).

Changes in v2:
- rebase on top of for-next branch

Fabrice Gasnier (4):
  dt-bindings: regulator: add support for the stm32-booster
  regulator: add support for the stm32-booster
  ARM: multi_v7_defconfig: enable STM32 booster regulator
  ARM: dts: stm32: add booster for ADC analog switches on stm32mp157c
