From 12ffe75819bb18b433642b21bbb5d1be7c0a1142 Mon Sep 17 00:00:00 2001 From: Manish Narani Date: Thu, 13 Feb 2020 23:37:30 -0700 Subject: arm64: zynqmp: Add 'no-1-8-v' property for ZynqMP Boards Modify dts files to add 'no-1-8-v' property for all the ZynqMP boards. User can remove this property to enable the UHS mode. This is to keep the same speed (HS) modes across all the stages of the Linux Boot. Due to power cycling limitation of some of the ZynqMP boards, some SD cards don't get power cycled and are failing in Linux.
