Subject: [PATCH 1/3] ARM: dts: stm32: add stpmic1 support on stm32mp157c ed1 board
Date: Wed, 3 Apr 2019 13:40:55 +0000 [thread overview]
Message-ID: <1554298852-9955-2-git-send-email-p.paillet@st.com> (raw)
In-Reply-To: <1554298852-9955-1-git-send-email-p.paillet@st.com>
This patch adds stpmic1 support on stm32mp157c ed1 board.
The STPMIC1 is a PMIC from STMicroelectronics. The STPMIC1 integrates 10
regulators, 3 power switches, a watchdog and an input for a power on key.
