Subject: [PATCH 6/6] ARM: tegra: paz00: enable wifi card
Date: Thu, 19 May 2011 14:08:30 +0200	[thread overview]
Message-ID: <1305806910-3903-7-git-send-email-marvin24@gmx.de> (raw)
In-Reply-To: <1305806910-3903-1-git-send-email-marvin24-Mmb7MZpHnFY@public.gmane.org>

The Wifi card attached to one usb port needs to be unkilled. The
corresponding gpio and also the gpio for the LED are exported to be
controlled by userspace later on.
