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

[Date Prev][Date Next][Thread Prev][Thread Next][Date Index][Thread Index]

 



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).
