Subject: [stable 4.19+][PATCH 02/20] ARM: dts: stm32: relax qspi pins slew-rate for stm32mp157
Date: Fri, 15 Nov 2019 15:33:38 -0700 [thread overview]
Message-ID: <20191115223356.27675-2-mathieu.poirier@linaro.org> (raw)
In-Reply-To: <20191115223356.27675-1-mathieu.poirier@linaro.org>
From: Patrice Chotard <patrice.chotard@st.com>
commit 86ec2e1739aa1d6565888b4b2059fa47354e1a89 upstream
Relax qspi pins slew-rate to minimize peak currents.
Fixes: 844030057339 ("ARM: dts: stm32: add flash nor support on stm32mp157c eval board")
