Merge tag 'clk-for-linus-3.16' of git://git.linaro.org/people/mike.turquette/linux into next
Pull clock framework updates from Mike Turquette:
"The clock framework changes for 3.16 are pretty typical: mostly clock
driver additions and fixes. There are additions to the clock core
code for some of the basic types (e.g. the common divider type has
some fixes and featured added to it).
One minor annoyance is a last-minute dependency that wasn't handled
quite right. Commit ba0fae3b06a6 ("clk: berlin: add core clock driver
for BG2/BG2CD") in this pull request depends on
include/dt-bindings/clock/berlin2.h, which is already in your tree via
the arm-soc pull request. Building for the berlin platform will break
when the clk tree is built on it's own, but merged into your master
branch everything should be fine"
