Merge tag 'clk-for-linus-3.18' of git://git.linaro.org/people/mike.turquette/linux
Pull clock tree updates from Mike Turquette:
"The clk tree changes for 3.18 are dominated by clock drivers. Mostly
fixes and enhancements to existing drivers as well as new drivers.
This tag contains a bit more arch code than I usually take due to some
OMAP2+ changes. Additionally it contains the restart notifier
handlers which are merged as a dependency into several trees.
The PXA changes are the only messy part. Due to having a stable tree
I had to revert one patch and follow up with one more fix near the tip
of this tag. Some dead code is introduced but it will soon become
live code after 3.18-rc1 is released as the rest of the PXA family is
converted over to the common clock framework.
Another trend in this tag is that multiple vendors have started to
push the complexity of changing their CPU frequency into the clock
driver, whereas this used to be done in CPUfreq drivers.
Changes to the clk core include a generic gpio-clock type and a
clk_set_phase() function added to the top-level clk.h api. Due to
some confusion on the fbdev mailing list the kernel boot parameters
documentation was updated to further explain the clk_ignore_unused
parameter, which is often required by users of the simplefb driver.
Finally some fixes to the locking around the clock debugfs stuff was
done to prevent deadlocks when interacting with other subsystems."
