351a102dbf ARM: drivers: remove __dev* attributes.
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,
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.

c2714334b9 ARM: arm-soc: Updates for Marvell mvebu/kirkwood
This is a branch with updates for Marvell's mvebu/kirkwood platforms. They
 came in late-ish, and were heavily interdependent such that it didn't
 make sense to split them up across the cross-platform topic branches. So
 here they are (for the second release in a row) in a branch on their own.

d356cf5a74 Dove: Fix irq_to_pmu()
PMU interrupts start at IRQ_DOVE_PMU_START, not IRQ_DOVE_PMU_START + 1.
Fix the condition.  (It may have been less likely to occur had the code
been written "if (irq >= IRQ_DOVE_PMU_START" which imho is the easier
to understand notation, and matches the normal way of thinking about
these things.)

5d3df93542 Dove: Attempt to fix PMU/RTC interrupts
Fix the acknowledgement of PMU interrupts on Dove: some Dove hardware
has not been sensibly designed so that interrupts can be handled in a
race free manner.  The PMU is one such instance.

The pending (aka 'cause') register is a bunch of RW bits, meaning that
these bits can be both cleared and set by software (confirmed on the
Armada-510 on the cubox.)

Hardware sets the appropriate bit when an interrupt is asserted, and
software is required to clear the bits which are to be processed.  If
we write ~(1 << bit), then we end up asserting every other interrupt
except the one we're processing.  So, we need to do a read-modify-write
cycle to clear the asserted bit.

However, any interrupts which occur in the middle of this cycle will
also be written back as zero, which will also clear the new interrupts.

The upshot of this is: there is _no_ way to safely clear down interrupts
in this register (and other similarly behaving interrupt pending
registers on this device.)  The patch below at least stops us creating
new interrupts.

Since we are going to use IOMEM() to define many base virtual
addresses, we can no longer use binary or to define the individual
register addresses ("binary or" arithmetic on pointers is not
allowed). Instead, use the more conventional plus operator to do so.

The binary or operators were actually not useful because the low-order
bits of the base address were always zero, so the usage of the binary
or operators was effectively identical to a plus operator.

01464226ac ARM: make mach/gpio.h headers optional
Most platforms don't need mach/gpio.h and it prevents multi-platform
kernel images. Add CONFIG_NEED_MACH_GPIO_H and make platforns select it
if they need gpio.h. This is platforms that define __GPIOLIB_COMPLEX
or have lots of implicit includes pulled in by mach/gpio.h.

at91 and omap have gpio clean-up pending and can drop
CONFIG_NEED_MACH_GPIO_H once that is in.

19ec6caca2 Merge branch 'cleanup/io-pci' into next/cleanups
From Rob Herring <robherring2@gmail.com>:

This is the 2nd part of mach/io.h removals. This series removes io.h on
platforms with PCI by creating a fixed virtual I/O mapping and a common
__io() macro.

This version has changed a bit to accommodate Tegra converting its PCIe
host to a platform driver. Now the virtual space is only reserved during
early boot before .map_io() is called. The mapping is not created until
calling pci_ioremap_io which can be done at any point after vmalloc is
initialized.

I've gone back to fixed 64K windows for each PCI bus. This allows
removing all the i/o resource setup from the individually platforms and
placing it within the common ARM PCI code.

I've only tested versatilepb under qemu (with the model hacked up to
actually enable i/o space), so any testing is appreciated. iop3xx and
mv78xx0 have some risk of breaking as the PCI bus addresses are moved
to 0 from matching the cpu host bus addesss.

* cleanup/io-pci:
  ARM: iop3xx: use fixed PCI i/o mapping
  ARM: mv78xx0: use fixed pci i/o mapping
  ARM: iop13xx: use fixed PCI i/o mapping
  iop13xx: use more regular PCI I/O space handling
  ARM: orion5x: use fixed PCI i/o mapping

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.

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.
