From d3e8b7569ad733c063a95dc1a51928e6e7c40652 Mon Sep 17 00:00:00 2001 From: Linus Walleij Date: Wed, 11 Jan 2012 09:51:14 +0100 Subject: [PATCH] ARM: plat-nomadik: handle clocking properly clk_prepare() was missing from the Nomadik MTU driver, also handle errors on prepare and enable in the simplest way possible, by bugging out - we cannot start the system without time anyway.
