Subject: [PATCH 1/5] Documentation: dt: iio: document stm32 adc trigger polarity
Date: Mon, 30 Jan 2017 14:57:39 +0100 [thread overview]
Message-ID: <1485784663-19505-2-git-send-email-fabrice.gasnier@st.com> (raw)
In-Reply-To: <1485784663-19505-1-git-send-email-fabrice.gasnier@st.com>
STM32 ADC trigger polarity can be set to either rising, falling
or both edges. Allow to configure it from dt.
