Subject: [PATCH 1/3] arm64: dts: st: add sdmmc1 node in stm32mp251 SoC file
Date: Mon, 4 Sep 2023 15:22:10 +0200 [thread overview]
Message-ID: <20230904132212.157405-2-yann.gautier@foss.st.com> (raw)
In-Reply-To: <20230904132212.157405-1-yann.gautier@foss.st.com>
The SDMMC1 peripheral is used for SD-cards (default on ST boards), or
eMMC cards. For the moment it uses the fixed clock ck_flexgen_51, until
clock driver is available.
