Subject: [PATCH 04/10] ARM: dts: stm32: update sdmmc slew-rate in stm32mp13 pinctrl
Date: Wed, 12 Jan 2022 17:32:20 +0100 [thread overview]
Message-ID: <20220112163226.25384-5-yann.gautier@foss.st.com> (raw)
In-Reply-To: <20220112163226.25384-1-yann.gautier@foss.st.com>
From: Gerald Baeza <gerald.baeza@foss.st.com>
SDMMC1/2 CK <= 50 MHz so slew-rate = <1>
A new node sdmmc1-clk-0 is added to manage the new clock pin slew-rate.
