Subject: [PATCH v7 07/14] arm/tegra: use PMC reset
Date: Wed, 14 Dec 2011 17:03:19 +0200	[thread overview]
Message-ID: <1323875032-18221-8-git-send-email-pdeschrijver@nvidia.com> (raw)
In-Reply-To: <1323875032-18221-1-git-send-email-pdeschrijver@nvidia.com>

Use PMC reset rather then CAR system reset as recommended by the hardware
team.
