510d573fef phy/micrel: Rename KS80xx to KSZ80xx
There is no such part as KS8001, KS8041 or KS8051. There are only
KSZ8001, KSZ8041 and KSZ8051. Rename these parts as such to match
the Micrel naming.

4f2d658b2f arm-soc: device tree description updates
This branch contains two kinds of updates: Some platforms in the process
 of getting converted to device tree based booting, and the platform
 specific patches necessary for that are included here. Other platforms
 are already converted, so we just need to update the actual device
 tree source files and the binding documents to add support for new board
 and new drivers.
 In the future we will probably separate those into two branches, and
 in the long run, the plan is to move the device tree source files out
 of the kernel repository, but that has to wait until we have completed
 a much larger portion of the binding documents.

813a95e5b4 arm-soc: soc-specific pinctrl changes
With this, five platforms are moving to the relatively new pinctrl
 subsystem for their pin management, replacing the older soc specific
 in-kernel interfaces with common code.
 
 There is quite a bit of net addition of code for each platform being
 added to the pinctrl subsystem. but the payback comes later when adding
 new boards can be done by only providing new device trees instead.

d1654b803f ARM: mxs: enable pinctrl dummy states
The mxs pinctrl driver will only support DT probe.  That said, the mxs
device drivers can only get pinctrl state from pinctrl subsystem when
the drivers get probed from device tree.

Before converting the whole mxs platform support over to device tree,
we need to enable pinctrl dummy states for those non-DT board files
to ensure the pinctrl API adopted by mxs device drivers will work for
both DT and non-DT probe.

Instead of calling pinctrl_provide_dummies() directly in every board
file, the patch introduces soc specific calls mx23_soc_init() and
mx28_soc_init() for boards' .init_machine hook to invoke, so that
any soc specific setup for non-DT boot only can be added there.

Pull "Disintegrate and delete asm/system.h" from David Howells:
 "Here are a bunch of patches to disintegrate asm/system.h into a set of
  separate bits to relieve the problem of circular inclusion
  dependencies.

  I've built all the working defconfigs from all the arches that I can
  and made sure that they don't break.

  The reason for these patches is that I recently encountered a circular
  dependency problem that came about when I produced some patches to
  optimise get_order() by rewriting it to use ilog2().

  This uses bitops - and on the SH arch asm/bitops.h drags in
  asm-generic/get_order.h by a circuituous route involving asm/system.h.

  The main difficulty seems to be asm/system.h.  It holds a number of
  low level bits with no/few dependencies that are commonly used (eg.
  memory barriers) and a number of bits with more dependencies that
  aren't used in many places (eg.  switch_to()).

  These patches break asm/system.h up into the following core pieces:

    (1) asm/barrier.h

        Move memory barriers here.  This already done for MIPS and Alpha.

    (2) asm/switch_to.h

        Move switch_to() and related stuff here.

    (3) asm/exec.h

        Move arch_align_stack() here.  Other process execution related bits
        could perhaps go here from asm/processor.h.

    (4) asm/cmpxchg.h

        Move xchg() and cmpxchg() here as they're full word atomic ops and
        frequently used by atomic_xchg() and atomic_cmpxchg().

    (5) asm/bug.h

        Move die() and related bits.

    (6) asm/auxvec.h

        Move AT_VECTOR_SIZE_ARCH here.

  Other arch headers are created as needed on a per-arch basis."

Fixed up some conflicts from other header file cleanups and moving code
around that has happened in the meantime, so David's testing is somewhat
weakened by that.  We'll find out anything that got broken and fix it..

These are all specific to some driver. They are typically the platform
 side of a change in the drivers directory, such as adding a new driver
 or extending the interface to the platform. In cases where there is no
 maintainer for the driver, or the maintainer prefers to have the
 platform changes in the same branch as the driver changes, the patches
 to the drivers are included as well.
 
 A much smaller set of driver updates that depend on other branches
 getting merged first will be sent later.

 In rtc-sa1100.c, the global removal of IRQF_DISABLED conflicts with
 the cleanup of the interrupt handling of that driver.

Merge tag 'drivers' of git://git.kernel.org/pub/scm/linux/kernel/git/arm/arm-soc

Pull "ARM: driver specific updates" from Arnd Bergmann:
 "These are all specific to some driver.  They are typically the
  platform side of a change in the drivers directory, such as adding a
  new driver or extending the interface to the platform.  In cases where
  there is no maintainer for the driver, or the maintainer prefers to
  have the platform changes in the same branch as the driver changes,
  the patches to the drivers are included as well.

  A much smaller set of driver updates that depend on other branches
  getting merged first will be sent later.

  The new export of tegra_chip_uid conflicts with other changes in
  fuse.c.  In rtc-sa1100.c, the global removal of IRQF_DISABLED
  conflicts with the cleanup of the interrupt handling of that driver.

1bfecd9358 ARM: board specific updates
These changes are all specific to one board only. We're trying to keep
 the number of board files low, but generally board level updates are
 ok on platforms that are working on moving towards DT based probing,
 which will eventually lead to removing them.
 
 The board-ams-delta.c board file gets a conflict between the removal of
 ams_delta_config and the addition of a lot of other data. The Kconfig
 file has two changes in the same line, and in exynos, the power domain
 cleanup conflicts with the addition of the image sensor device.
