[GIT PULL 4/8] arm-soc: clock driver changes
From: Olof Johansson
Date: Sat May 26 2012 - 03:24:18 EST
The new clock subsystem was merged in linux-3.4 without any users, this
now moves the first three platforms over to it: imx, mxs and spear.
The series also contains the changes for the clock subsystem itself,
since Mike preferred to have it together with the platforms that require
these changes, in order to avoid interdependencies and conflicts.
