This is from linux-next-2012-07-19 plus two patches from Shawn Guo:
[PATCH v2 1/2] clk: fix clk_get on of_clk_get_by_name return check
[PATCH v2 2/2] clk: fix compile for OF && !COMMON_CLK

Especialy the second one is needed to get the system booting.

Config is more or less mxs_defconfig, with a few additional drivers
enabled.
