This series adds support for SYSCFG bits that control ADC analog switches supply on STM32MP1 and STM32H7. The ADC inputs are multiplexed with analog switches which have reduced performances when their supply is below 2.7V. Analog switches supply can be controlled using SYSCFG bits, to reach full ADC performance.
