Subject: [PATCH] mmc: mmci: add st,stm32-sdmmc2 compatible
Date: Fri, 10 Dec 2021 10:18:34 +0100	[thread overview]
Message-ID: <20211210091834.28958-1-yann.gautier@foss.st.com> (raw)

Although this compatible is not used in kernel, as we use the common
MMCI driver, it is used by bootloaders. The U-Boot driver was merged
before the kernel driver and uses this compatible.
To avoid issues when aligning device tree files between kernel and
boot loader, the ST dedicated compatible is added to bindings file.
