From: Ng Tze Yee Date: Tue, 24 Feb 2026 06:01:55 +0000 (-0800) Subject: arm64: dts: socfpga: stratix10: Add emmc support X-Git-Url: http://git.ipfire.org/gitweb.cgi?a=commitdiff_plain;h=4bc04eb90b7c76216bdbe00f48e36967abb8c7af;p=thirdparty%2Fkernel%2Fstable.git arm64: dts: socfpga: stratix10: Add emmc support The Stratix10 devkit supports a separate eMMC daughter card. The eMMC daughter card replaces the SDMMC slot that is on the default daughter card and thus requires a separate board dts file.
