Subject: [PATCH 2/3] arm64: dts: st: add sdmmc2 pins on stm32mp25
Date: Sat, 12 Sep 2026 20:45:05 +0000 [thread overview]
Message-ID: <20260912204454.219606-3-mateusz.nowicki@posteo.net> (raw)
In-Reply-To: <20260912204454.219606-1-mateusz.nowicki@posteo.net>
Add the 8-bit bus pin groups of SDMMC2 on port E, used by the eMMC
on the STM32MP257F-DK.
