b8edf848e9 ARM: arm-soc: multiplatform conversion patches
Here are more patches in the progression towards multiplatform, sparse
 irq conversions in particular.
 
 Tegra has a handful of cleanups and general groundwork, but is
 not quite there yet on full enablement.
 
 Platforms that are enabled through this branch are VT8500 and Zynq. 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
 new platforms for this merge window, sunxi and bcm, were merged with
 multiplatform support enabled.

9cd11c0c47 ARM: soc: multiplatform enablement
This is a pretty significant branch. It's the introduction of the
 first multiplatform support on ARM, and with this (and the later
 branch) merged, it is now possible to build one kernel that contains
 support for highbank, vexpress, mvebu, socfpga, and picoxcell. More
 platforms will be convered over in the next few releases.
 
 Two critical last things had to be done for this to be practical and
 possible:
 * Today each platform has its own include directory under
   mach-<mach>/include/mach/*, and traditionally that is where a lot of
   driver/platform shared definitions have gone, such as platform data
   structures. They now need to move out to a common location instead,
   and this branch moves a large number of those out to
   include/linux/platform_data.
 * Each platform used to list the device trees to compile for its
   boards in mach-<mach>/Makefile.boot.
 
 Both of the above changes will mean that there are some merge
 conflicts to come (and some to resolve here). It's a one-time move and
 once it settles in, we should be good for quite a while. Sorry for the
 overhead.

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.

Pull PWM subsystem from Thierry Reding:
 "The new PWM subsystem aims at collecting all implementations of the
  legacy PWM API and to eventually replace it completely.

  The subsystem has been in development for over half a year now and
  many drivers have already been converted.  It has been in linux-next
  for a couple of weeks and there have been no major issues so I think
  it is ready for inclusion in your tree."

Arnd Bergmann <arnd@arndb.de>:
 "Very much Ack on the new subsystem.  It uses the interface
  declarations as the previously separate pwm drivers, so nothing
  changes for now in the drivers using it, although it enables us to
  change those more easily in the future if we want to.

  This work is also one of the missing pieces that are required to
  eventually build ARM kernels for multiple platforms, which is
  currently prohibited (amongs other things) by the fact that you cannot
  have more than one driver exporting the pwm functions."

40c6d8aee4 ARM: 7022/1: allow to detect conflicting zreladdrs
Boards used to specify zreladdr in their Makefile.boot with
zreladdr-y := x, so conflicting zreladdrs were silently overwritten.
This patch changes this to zreladdr-y += x, so that we end
up with multiple words in zreladdr in such a case. We can
detect this later and complain if necessary.

639da5ee37 ARM: add an extra temp register to the low level debugging addruart macro
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.

8f3c4537bb ARM: gpio: make trivial GPIOLIB implementation the default
Rather than marking the mach/gpio.h header files which want to use the
trivial GPIOLIB implementation, mark those which do not want to use it
instead.  This means that by default, you get the trivial implementation
and only have to do something extra if you need to.  This should
encourage the use of the trivial default implementation.

As an additional bonus, several gpio.h header files become empty.

01e7dc89d0 ARM: gpio: consolidate gpio_to_irq
Many of the gpio_to_irq implementations use the gpiolib version of this
function.  Provide the standard gpiolib gpio_to_irq() for everyone, but
allow platforms to override it if they wish.  Add the neccessary
overrides for those platforms which do not use the standard definition.

21f47fbc5b ARM: 6597/1: Add basic architecture support for VIA/WonderMedia 85xx SoC's
This adds support for the family of Systems-on-Chip produced initially
by VIA and now its subsidiary WonderMedia that have recently become
widespread in lower-end Chinese ARM-based tablets and netbooks.

Support is included for both VT8500 and WM8505, selectable by a
configuration switch at kernel build time.

Included are basic machine initialization files, register and
interrupt definitions, support for the on-chip interrupt controller,
high-precision OS timer, GPIO lines, necessary macros for early debug,
pulse-width-modulated outputs control, as well as platform device
configurations for the specific drivers implemented elsewhere.
