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.

b1b3f49ce4 ARM: config: sort select statements alphanumerically
As suggested by Andrew Morton:

  This is a pet peeve of mine.  Any time there's a long list of items
  (header file inclusions, kconfig entries, array initalisers, etc) and
  someone wants to add a new item, they *always* go and stick it at the
  end of the list.

  Guys, don't do this.  Either put the new item into a randomly-chosen
  position or, probably better, alphanumerically sort the list.

lets sort all our select statements alphanumerically.  This commit was
created by the following perl:

while (<>) {
	while (/\\\s*$/) {
		$_ .= <>;
	}
	undef %selects if /^\s*config\s+/;
	if (/^\s+select\s+(\w+).*/) {
		if (defined($selects{$1})) {
			if ($selects{$1} eq $_) {
				print STDERR "Warning: removing duplicated $1 entry\n";
			} else {
				print STDERR "Error: $1 differently selected\n".
					"\tOld: $selects{$1}\n".
					"\tNew: $_\n";
				exit 1;
			}
		}
		$selects{$1} = $_;
		next;
	}
	if (%selects and (/^\s*$/ or /^\s+help/ or /^\s+---help---/ or
			  /^endif/ or /^endchoice/)) {
		foreach $k (sort (keys %selects)) {
			print "$selects{$k}";
		}
		undef %selects;
	}
	print;
}
if (%selects) {
	foreach $k (sort (keys %selects)) {
		print "$selects{$k}";
	}
}

It found two duplicates:

Warning: removing duplicated S5P_SETUP_MIPIPHY entry
Warning: removing duplicated HARDIRQS_SW_RESEND entry

and they are identical duplicates, hence the shrinkage in the diffstat
of two lines.

We have four testers reporting success of this change (Tony, Stephen,
Linus and Sekhar.)

9cd11c0c47 Merge tag 'multiplatform' of git://git.kernel.org/pub/scm/linux/kernel/git/arm/arm-soc
Pull ARM soc multiplatform enablement from Olof Johansson:
 "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."

Fix conflicts as per Olof.

   - A number of cleanup series for OMAP, moving and removing some
     headers, sparse irq rework and in general preparation for
     multiplatform.
   - Final removal of all non-DT boards for Tegra, it is now
     device-tree-only!
   - Removal of a stale platform, nxp4008.  It's an old mobile chipset
     that is no longer in use, and was very likely never really used
     with a mainline kernel.  We have not been able to find anyone
     interested in keeping it around in the kernel.

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.

28e8e29c61 ARM: consolidate pen_release instead of having per platform definitions
Almost each SMP platform defines pen_release to manage booting secondary
CPUs. This of course clashes with the single zImage effort.

Add the pen_release definition to the ARM SMP code, and remove all others.
This should only be used by platforms which lack any kind of CPU power
management...

4312a7ef9c ARM: msm: Allow timer.c to compile on multiple targets
The timer code relies on #defines from mach/iomap.h, cpu_is_*()
checks, and a global irq #define. All this makes this file
impossible to compile in a mult-target build. Therefore, make a
sys_timer struct for each SoC so that machine descriptors can
reference the correct timer. Then go through and replace all the
defines with raw values that are passed to a common
initialization function.

This paves the way to adding DT support to this code as well as
allows us to compile this file on multiple targets at the same
time.
