Subject: [PATCH 2/14] ARM: LPC32xx: Clock initialization for NAND controllers
Date: Mon, 11 Jun 2012 13:02:05 +0200	[thread overview]
Message-ID: <1339412537-24485-3-git-send-email-stigge@antcom.de> (raw)
In-Reply-To: <1339412537-24485-1-git-send-email-stigge@antcom.de>

This patch adds clock initialization for the MLC NAND controller of the LPC32xx
SoC and adjusts it for the SLC controller.

Signed-off-by: Roland Stigge <stigge@antcom.de>
