Subject: [PATCH 3/3] ARM: dts: stm32: add ADC analog switches syscfg on stm32mp157c
Date: Wed, 12 Jun 2019 09:24:36 +0200 [thread overview]
Message-ID: <1560324276-681-4-git-send-email-fabrice.gasnier@st.com> (raw)
In-Reply-To: <1560324276-681-1-git-send-email-fabrice.gasnier@st.com>
On stm32mp157c, the ADC inputs are multiplexed with analog switches which
have reduced performances when their supply is below 2.7V (vdda by
default).
Add syscfg registers that can be used on stm32mp157c, to get full ADC
analog performances.
