The Marvell Kirkwood SoCs have simple cpufreq support in hardware. The
CPU can either use the a high speed cpu clock, or the slower DDR
clock. Add a driver to swap between these two clock sources.

Intel Lynxpoint Low Power Subsystem hosts peripherals like UART, I2C and
SPI controllers. For most of these there is a configuration register that
allows software to enable and disable the functional clock. Disabling the
clock while the peripheral is not used saves power.
In order to take advantage of this we add a new clock gate of type
lpss_gate that just re-uses the ordinary clk_gate but in addition is able
to enumerate the base address register of the device using ACPI.
We then create a clock tree that models the Lynxpoint LPSS clocks using
these gates and fixed clocks so that we can pass clock rate to the drivers
as well.

Pull clock framework update from Michael Turquette:
"The common clock framework changes for 3.9 are almost entirely fixes.
None are dire enough to be Cc'd to stable which may be interpreted to
mean that users of the framework are reaching stability. Lots of new
adoption of this framework is via DeviceTree data and that comes
through the respective architecture and platform trees instead of
through the clk framework tree.
Two new features are improved debugfs output and an improvement to how
DT clocks are initialized by reusing a common method."

Patch 85a18198 "clk: sunxi: Use common of_clk_init() function"
removed the clk-sunxi.c file but left the Makefile entry, which
causes a build error in multi_v7_defconfig:
make[4]: *** No rule to make target `drivers/clk/clk-sunxi.o', needed by `drivers/clk/built-in.o'.
The obvious fix is to remove the extraneous line from the

this patche deletes hard code that registers clkdev by things like:
clk_register_clkdev(clk, NULL, "b0030000.nand");
clk_register_clkdev(clk, NULL, "b0040000.audio");
clk_register_clkdev(clk, NULL, "b0080000.usp");
prima2 clock controller becomes a clock provider and every dt node
just declares its clock sources by dt prop.
it also makes us easier to extend this driver to support both prima2
and marco as marco has different address mapping with prima2.

The clk_lookup entry is dropped at remove time by a call to
clkdev_drop(). That function frees the entry, which is also freed by the
driver core as it has been allocated through devm_kzalloc(). This
results in a double free.
Use kzalloc() instead of devm_kzalloc() to fix this.

When calculating device clock divisor values in set_rate and
round_rate, we do a simple integer divide. If parent_rate / rate
has a fraction, this is dropped which results in the device clock
being set too high.
This patch corrects the problem by adding 1 to the calculated
divisor if the division would have had a decimal result.

This fixes the following error when building for arm-imx:
> ERROR: "__clk_get_name" [drivers/staging/imx-drm/ipu-v3/imx-ipu-v3.ko] undefined!
> make[1]: *** [__modpost] Error 1
> make: *** [modules] Error 2
There are valid usecases to get the name of a clock, be it for debugging
purposes or to register a children of a clock like done in this IPU driver.
Therefore exporting __clk_get_name() and make it available for others makes
sense.

The helper functions that access the opaque struct clk should
not be marked inline since they are contained in clk.c, but expected
to be used by other compilation units. This causes compile errors
under gcc-4.7

Pull ARM SoC fixes from Olof Johansson:
"People are back from the holiday breaks, and it shows. Here are a
bunch of fixes for a number of platforms:
- A couple of small fixes for Nomadik
- A larger set of changes for kirkwood/mvebu
- uart driver selection, dt clocks, gpio-poweroff fixups, a few
__init annotation fixes and some error handling improvement in
their xor dma driver.
- i.MX had a couple of minor fixes (and a critical one for flexcan2
clock setup)
- MXS has a small board fix and a framebuffer bugfix
- A set of fixes for Samsung Exynos, fixing default bootargs and some
Exynos5440 clock issues
- A set of OMAP changes including PM fixes and a few sparse warning
fixups
All in all a bit more positive code delta than we'd ideally want to
see here, mostly from the OMAP PM changes, but nothing overly crazy."

CONFIG_HOTPLUG is going away as an option. As a result, the __dev*
markings need to be removed.
This change removes the use of __devinit, __devexit_p, __devinitdata,
__devinitconst, and __devexit from these drivers.
Based on patches originally written by Bill Pemberton, but redone by me
in order to handle some of the coding style issues better, by hand.

The Nomadik NAND driver is really just a subset of the existing
FSMC driver, so let's switch over to using that driver instead,
since it handles more variants of this chip. The callbacks for
setting up the chip is doing stuff now handled by the FSMC
driver.

This driver allows to provide DT clocks for core clocks found on
Marvell Kirkwood, Dove & 370/XP SoCs. The core clock frequencies and
ratios are determined by decoding the Sample-At-Reset registers.
Although technically correct, using a divider of 0 will lead to
div_by_zero panic. Let's use a ratio of 0/1 instead to fail later
with a zero clock.

Note that i.MX was converted in one of the earlier cleanup branches as
well (before we started a separate topic for multiplatform). And both

multiplatform support enabled."
