Subject: [PATCH 07/10] ARM i.MX27: Add lcdc per gate
Date: Mon,  8 Oct 2012 21:44:16 +0200	[thread overview]
Message-ID: <1349725459-20226-8-git-send-email-s.hauer@pengutronix.de> (raw)
In-Reply-To: <1349725459-20226-1-git-send-email-s.hauer@pengutronix.de>

This gate is used to enable/disable the lcd controller, hence we
need a gate for it.
