Merge tag 'clk-for-linus-3.14-part1' of git://git.linaro.org/people/mike.turquette/linux
Pull clk framework changes from Mike Turquette:
"The first half of the clk framework pull request is made up almost
entirely of new platform/driver support. There are some conversions
of existing drivers to the common-clock Device Tree binding, and a few
non-critical fixes to the framework.
Due to an entirely unnecessary cyclical dependency with the arm-soc
tree this pull request is broken into two pieces. The second piece
will be sent out after arm-soc sends you the pull request that merged
in core support for the HiSilicon 3620 platform. That same pull
request from arm-soc depends on this pull request to merge in those
HiSilicon bits without causing build failures"
[ Just did the ARM SoC merges, so getting ready for the second clk tree
pull request - Linus ]
