Subject: [PATCH 1/3] dt-bindings: iio: stm32-adc: add support for STM32MP1.
Date: Wed, 18 Apr 2018 17:37:52 +0200	[thread overview]
Message-ID: <1524065874-434-2-git-send-email-fabrice.gasnier@st.com> (raw)
In-Reply-To: <1524065874-434-1-git-send-email-fabrice.gasnier@st.com>

Document support for STM32MP1 ADC. It's quite similar to STM32H7 ADC.
Introduce "st,stm32mp1-adc" compatible to handle variants of this
hardware such as vregready flag, interrupts, clock rate.
