From 621e70bca592b7897c1ff89d182b94864d2216eb Mon Sep 17 00:00:00 2001 From: Michal Simek Date: Thu, 5 Aug 2021 15:50:29 +0200 Subject: [PATCH] arm64: versal: Do not enable SD HS mode for vck190/vmk180 Current SD level shifter is EOL and needs to be replaced by another part. Boards with it are going to production soon without any infrastructure for recongition if this is old/new board. Till this is done do not use HS mode and limit maximum frequence till 19MHz.
