This patch extends nodes of PMU system controller on Exynos4210, 4x12,
5250 and 5420 SoCs with newly defined properties used by Exynos CLKOUT
driver.

This patch introduces a driver that handles configuration of CLKOUT pin
of Exynos SoCs that can be used to output certain clocks from inside of
the SoC to a dedicated output pin.

Exynos4 has saveral PPMUs and each of them has operation clock which

CLK_PPMUMFC_R, CLK_G3D, CLK_PPMUIMAGE, CLK_PPMULCD0, CLK_PPMULCD1,

The "aclk66_peric" clock is a gate clock with a whole bunch of gates
underneath it.  This big gate isn't very useful to include in our
clock tree.  If any of the children need to be turned on then the big
gate will need to be on anyway.  ...and there are plenty of other "big
gates" that aren't described in our clock tree, some of which shut off
collections of clocks that have no relationship in the hierarchy so
are hard to model.

"aclk66_peric" is causing earlyprintk problems since it gets disabled
as part of the boot process, so let's just remove it.

Strangely (and for no good reason) this clock is exported as part of
the common clock bindings.  Remove it since there are no in-kernel
device trees using it and no reason anyone out of tree should refer to
it either.

In the move to this clock driver the hookups for the SPI clocks were
dropped, which causes my system Cragganmore (s3c6410 based) to be unable
to locate any spibus clocks. This patch adds them back in.

When taking the clock from the epll clock (SCLK) the rates on the SPI
bus are incorrect, this needs further debugging but the hookup here
should be correct and the problem should be else where.

The USBCLK case has been dropped because this requires the USB PHY to be
enabled.

Pull i2c new drivers from Wolfram Sang:
 "Here is a pull request from i2c hoping for the "new driver" rule.

  Originally, I wanted to send this request during the merge window, but
  code checkers with very recent additions complained, so a few fixups
  were needed.  So, some more time went by and I merged rc1 to get a
  stable base"

So the "new driver" rule is really about drivers that people absolutely
need for the kernel to work on new hardware, which is not so much the
case for i2c.  So I considered not pulling this, but eventually
relented.

Just for FYI: the whole (and only) point of "new drivers" is not that
new drivers cannot regress things (they can, and they have - by
triggering badly tested code on machines that never triggered that code
before), but because they can bring to life machines that otherwise
wouldn't be useful at all without the drivers.

So the new driver rule is for essential things that actual consumers
would care about, ie devices like networking or disk drivers that matter
to normal people (not server people - they run old kernels anyway, so
mainlining new drivers is irrelevant for them).

If connector->dpms is left untouched, it defaults
to DRM_MODE_DPMS_ON (0).

As a result, drm_helper_connector_dpms will exit when
it will be asked to set the state to DRM_MODE_DPMS_ON,
because it is already set.

That issue prevented displays from turning on at boot.

tdev->dev has been freed in device_destroy(), it's not right to
use dev_set_drvdata() after that;

This config exists entirely to hide the cpufreq menu from the
kernel configuration unless a platform has selected it. Nothing
is actually built if this config is 'Y' and it just leads to more
patches that add a select under a platform Kconfig so that some
other CPUfreq option can be chosen. Let's remove the option so
that we can always enable CPUfreq drivers on unicore32 platforms.
