Subject: [PATCH 3/3] ARM: i.MX51 efikasb: call imx51_lowlevel_init from lowlevel init
Date: Mon, 17 Jun 2013 11:17:53 +0200 [thread overview]
Message-ID: <1371460673-14284-3-git-send-email-s.hauer@pengutronix.de> (raw)
In-Reply-To: <1371460673-14284-1-git-send-email-s.hauer@pengutronix.de>
Adjusting the PLLs when MMU/caching is already enabled seems to be
unstable on the Smartbook, so do it during early init.
