Subject: [PATCH 4/6] ARM: dts: stm32: Enable sdio1 for stm32f769-disco
Date: Thu, 1 Mar 2018 10:43:39 +0100 [thread overview]
Message-ID: <1519897421-23803-5-git-send-email-patrice.chotard@st.com> (raw)
In-Reply-To: <1519897421-23803-1-git-send-email-patrice.chotard@st.com>
From: Patrice Chotard <patrice.chotard@st.com>
Adds SDIO related DT nodes for stm32f769-disco board.
broken-cd property is needed as it misses a pullup on board
(resistor R76 is missing).
Signed-off-by: Patrice Chotard <patrice.chotard@st.com>
