Subject: [PATCH v2 5/5] ARM: dts: AM335x-evmsk: Do not reset gpio0
Date: Wed, 9 Oct 2013 15:42:01 +0530 [thread overview]
Message-ID: <1381313521-10422-6-git-send-email-rnayak@ti.com> (raw)
In-Reply-To: <1381313521-10422-1-git-send-email-rnayak@ti.com>
Do not reset GPIO0 at boot-up because GPIO0 is used
on AM335x EVM-SK to control VTT regulators on DDR3.
Without this EVM-SK boards fail to boot-up because
of DDR3 corruption.
