Merge tag 'clk-for-linus-3.10' of git://git.linaro.org/people/mturquette/linux
Pull clock framework update from Michael Turquette:
"The common clock framework changes for 3.10 include many fixes for
existing platforms, as well as adoption of the framework by new
platforms and devices.
Some long-needed fixes to the core framework are here as well as new
features such as improved initialization of clocks from DT as well as
framework reentrancy for nested clock operations."
