Subject: [PATCH 06/15] ARM i.MX: Use platform_device_id for gpio driver
Date: Wed, 12 Sep 2012 22:06:38 +0200 [thread overview]
Message-ID: <1347480407-16865-7-git-send-email-s.hauer@pengutronix.de> (raw)
In-Reply-To: <1347480407-16865-1-git-send-email-s.hauer@pengutronix.de>
So we get the type of the gpio controller from the device
