Subject: [PATCH] ARM: dts: am437x-gp-evm: Do not reset gpio5
Date: Fri, 21 Mar 2014 10:50:13 +0530 [thread overview]
Message-ID: <1395379213-15451-1-git-send-email-lokeshvutla@ti.com> (raw)
From: Dave Gerlach <d-gerlach@ti.com>
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.
