From: Josua Mayer Date: Thu, 11 Sep 2025 18:28:05 +0000 (+0200) Subject: arm64: dts: marvell: cn9132-clearfog: disable eMMC high-speed modes X-Git-Tag: v6.16.10~28 X-Git-Url: http://git.ipfire.org/gitweb.cgi?a=commitdiff_plain;h=eca259860a084513ccc006d739ae76a744ab3098;p=thirdparty%2Fkernel%2Fstable.git arm64: dts: marvell: cn9132-clearfog: disable eMMC high-speed modes commit 48b51799a5461707705454568453618cdd7307f4 upstream. Similar to MacchiatoBIN the high-speed modes are unstable on the CN9132 CEX-7 module, leading to failed transactions under normal use. Disable all high-speed modes including UHS. Additionally add no-sdio and non-removable properties as appropriate for eMMC.
