Subject: [PATCH 0/3] STM32 ADC analog switches supply control
Date: Wed, 12 Jun 2019 09:24:33 +0200 [thread overview]
Message-ID: <1560324276-681-1-git-send-email-fabrice.gasnier@st.com> (raw)
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.
