Subject: [PATCH v3] ARM: dts: stm32: Add ADC support to stm32mp157c
Date: Tue, 22 May 2018 17:45:37 +0200 [thread overview]
Message-ID: <1527003937-15999-1-git-send-email-fabrice.gasnier@st.com> (raw)
stm32mp157c has an ADC block with two physical ADCs.
Signed-off-by: Fabrice Gasnier <fabrice.gasnier@st.com>
