From 1ff3859e7ea134c09512498aa2251fd3a57d250d Mon Sep 17 00:00:00 2001 From: Dave Gerlach Date: Fri, 21 Mar 2014 10:50:13 +0530 Subject: ARM: dts: am437x-gp-evm: Do not reset gpio5 Do not reset GPIO5 at boot-up because GPIO5_7 is used on AM437x GP-EVM to control VTT regulators on DDR3. Without this some GP-EVM boards will fail to boot because of DDR3 corruption.
