Merge tag 'clk-for-linus' of git://git.linaro.org/people/mturquette/linux
Pull clock framework changes from Mike Turquette:
"The common clock framework changes for 3.8 are comprised of lots of
fixes for existing platforms as well as new ports for some ARM
platforms. In addition there are new clk drivers for audio devices
and MFDs."
Fix up trivial conflict in <linux/clk-provider.h> (removal of 'inline'
clashing with return type fixes)
