Merge tag 'clk-for-linus-3.15' of git://git.linaro.org/people/mike.turquette/linux
Pull clock framework changes from Mike Turquette:
"The clock framework changes for 3.15 look similar to past pull
requests. Mostly clock driver updates, more Device Tree support in
the form of common functions useful across platforms and a handful of
features and fixes to the framework core"
