From 9aa4302c02de12517bf08d0fc487bf4da290c3e2 Mon Sep 17 00:00:00 2001 From: Faiz Abbas Date: Thu, 4 Feb 2021 15:11:04 +0530 Subject: [PATCH] arm: dts: k3-am654-base-board: Limit Sd card to High speed modes There's an issue with the base board in which the power cycle circuit takes way longer to power down than expected by mmc core. code. This prevents the card from enumerating in UHS modes. Disable UHS modes for this board until a new board revision fixes the issue.
