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."

Add a the common code used by all PXA variants.
This is the first step in the transition from architecture defined
clocks (in arch/arm/mach-pxa) towards clock framework. The goal is to
have the same features (and not all the features) of the existing
clocks, and enable the transition of PXA to device-tree.
All PXA rely on a "CKEN" type clock, which :
- has a gate (bit in CKEN register)
- is generated from a PLL, generally divided
- has an alternate low power clock
Each variant will specialize the CKEN clock :
- pxa25x have no low power clock
- pxa27x in low power use always the 13 MHz ring oscillator
- pxa3xx in low power have specific dividers for each clock
The device-tree provides a list of CLK_* (ex: CLK_USB or CLK_I2C) to get
a handle on the clock. While pxa-clock.h will describe all the clocks of
all the variants, each variant will only use a subset of it.

Add clock provider for clocks in DMC domain including EPLL and BPLL. The
DMC clocks are necessary for Exynos3 devfreq driver.
The DMC clock domain uses different address space (0x105C0000) than
standard clock domain (0x10030000 - 0x10050000). The difference is huge
enough to add new DT node for the clock provider, rather than extending
existing address space.
