Subject: [PATCH 2/3] ARM: dts: stm32: add ADC pins used on stm32mp157a-dk1
Date: Fri, 13 Sep 2019 16:34:39 +0200 [thread overview]
Message-ID: <1568385280-2633-3-git-send-email-fabrice.gasnier@st.com> (raw)
In-Reply-To: <1568385280-2633-1-git-send-email-fabrice.gasnier@st.com>
Define pins that can be used for ADC on stm32mp157a-dk1 board:
- AIN connector has ADC input pins
- USB Type-C CC1 & CC2 pins (e.g. in18, in19)
