Arnaud Patard (Rtp) 58569aee5a ARM: Orion: Set eth packet size csum offload limit
The mv643xx ethernet controller limits the packet size for the TX
checksum offloading. This patch sets this limits for Kirkwood and
Dove which have smaller limits that the default.

As a side note, this patch is an updated version of a patch sent some years
ago: http://lists.infradead.org/pipermail/linux-arm-kernel/2010-June/017320.html
which seems to have been lost.

Andrew Lunn 278b45b06b ARM: Orion: DT support for IRQ and GPIO Controllers
Both IRQ and GPIO controllers can now be represented in DT.  The IRQ
controllers are setup first, and then the GPIO controllers. Interrupts
for GPIO lines are placed directly after the main interrupts in the
interrupt space.

Commit 0fa1f0609a (ARM: Orion: Fix
Virtual/Physical mixup with watchdog) broke the Dove & MV78xx0
build. Although these two SoC don't use the watchdog, the shared
platform code still needs to build. Add the necessary defines.

Linus Torvalds 2795343705 arm-soc: clock driver changes
The new clock subsystem was merged in linux-3.4 without any users, this
 now moves the first three platforms over to it: imx, mxs and spear.
 
 The series also contains the changes for the clock subsystem itself,
 since Mike preferred to have it together with the platforms that require
 these changes, in order to avoid interdependencies and conflicts.

Linus Torvalds 9bc747bea5 arm-soc: First batch of cleanups
These cleanups are basically all over the place. The idea is to collect
 changes with minimal impact but large number of changes so we can avoid
 them from distracting in the diffstat in the other series.
 
 A significant number of lines get removed here, in particular because
 the ixp2000 and ixp23xx platforms get removed. These have never been
 extremely popular and have fallen into disuse over time with no active
 maintainer taking care of them. The u5500 soc never made it into a
 product, so we are removing it from the ux500 platform.
 
 Many good cleanups also went into the at91 and omap platforms, as has
 been the case for a number of releases.

Russell King daeb4c0c3b ARM: PCI: get rid of pci_std_swizzle()
Most PCI implementations use the standard PCI swizzle function, which
handles the well defined behaviour of PCI-to-PCI bridges which can be
found on cards (eg, four port ethernet cards.)

Rather than having almost every platform specify the standard swizzle
function, make this the default when no swizzle function is supplied.
Therefore, a swizzle function only needs to be provided when there is
something exceptional which needs to be handled.

This gets rid of the swizzle initializer from 47 files, and leaves us
with just two platforms specifying a swizzle function: ARM Integrator
and Chalice CATS.

  Beyond that, I'm handing off PCI maintainership to Bjorn Helgaas.

  kindly volunteered to take over.  I just don't feel I have the time

The patch "ARM: orion: Consolidate USB platform setup code.", commit
4fcd3f374a broke USB on TS-7800 and
other orion5x boards, because the wrong type of PHY was being passed
to the EHCI driver in the platform data. Orion5x needs EHCI_PHY_ORION
and all the others want EHCI_PHY_NA.

Allow the mach- code to tell the generic plat-orion code which USB PHY
enum to place into the platform data.

Version 2: Rebase to v3.3-rc2.

no longer does anything useful.

For samsung platforms, remove the include of mach/system-reset.h and
plat/system-reset.h from their respective mach/system.h headers as these
just define their arch_reset functions.  As a result, the s3c2410 and
plat-samsung system-reset.h files are no longer referenced, so remove
these files entirely.

Some platforms (like OMAP not to name it) are doing rather complicated
hacks just to determine the base UART address to use.  Let's give their
addruart macro some slack by providing an extra work register which will
allow for much needed cleanups.

This is basically a no-op as this commit is only adding the extra argument
to the macro but no one is using it yet.

Ralf Baechle d5341942d7 PCI: Make the struct pci_dev * argument of pci_fixup_irqs const.
Aside of the usual motivation for constification,  this function has a
history of being abused a hook for interrupt and other fixups so I turned
this function const ages ago in the MIPS code but it should be done
treewide.

Due to function pointer passing in varous places a few other functions
had to be constified as well.
