Subject: [PATCH v2 4/4] ARM: dts: stm32: add booster for ADC analog switches on stm32mp157c
Date: Mon, 1 Jul 2019 10:14:25 +0200 [thread overview]
Message-ID: <1561968865-22037-5-git-send-email-fabrice.gasnier@st.com> (raw)
In-Reply-To: <1561968865-22037-1-git-send-email-fabrice.gasnier@st.com>
Booster for ADC analog input switches can be used when Vdda is below 2.7V
to get maximum ADC analog performances.
Add booster for ADC analog switches on stm32mp157c.
