27873b052e ARM: samsung: make SAMSUNG_DMADEV optional
The only remaining driver using the samsung dmadev code is the broken
samsung-ac97 sound driver. However, as found by Russell's autobuilder,
the elaborate dependency chains around it cause problems with
circular dependencies.

This is an attempt to simplify those dependencies by making the
SAMSUNG_DMADEV option user-selectable. I also try to keep the
default settings for all related options unchanged, so we don't
introduce any regressions against earlier testing on linux-next.

In particular, all s3c64xx and s5p* platforms keep selecting the
pl330 and pl08x drivers they require, but the select statement
is now moved towards the main platform option, and it remains
optional by unselecting CONFIG_DMADEVICES.

2bf73dd61a ARM: SoC: late cleanups
These could not be part of the first cleanup branch, because they either
 came too late in the cycle, or they have dependencies on other branches.
 Important changes are:
 
 * The integrator platform is almost multiplatform capable after
   some reorganization (Linus Walleij)
 * Minor cleanups on Zynq (Michal Simek)
 * Lots of changes for Exynos and other Samsung platforms, including
   further preparations for multiplatform support and the clocks bindings
   are rearranged.

platforms that are not (yet) converted to multi-platform.

While at it there are no users of CLOCK_TICK_RATE any more, so also drop

6fa52ed33b ARM: arm-soc driver changes for 3.10
This is a rather large set of patches for device drivers that for one
 reason or another the subsystem maintainer preferred to get merged
 through the arm-soc tree. There are both new drivers as well as
 existing drivers that are getting converted from platform-specific
 code into standalone drivers using the appropriate subsystem
 specific interfaces.
 
 In particular, we can now have pinctrl, clk, clksource and irqchip
 drivers in one file per driver, without the need to call into
 platform specific interface, or to get called from platform specific
 code, as long as all information about the hardware is provided
 through a device tree.
 
 Most of the drivers we touch this time are for clocksource. Since
 now most of them are part of drivers/clocksource, I expect that we
 won't have to touch these again from arm-soc and can let the
 clocksource maintainers take care of these in the future.
 
 Another larger part of this series is specific to the exynos platform,
 which is seeing some significant effort in upstreaming and
 modernization of its device drivers this time around, which
 unfortunately is also the cause for the churn and a lot of the
 merge conflicts.
 
 There is one new subsystem that gets merged as part of this series:
 the reset controller interface, which is a very simple interface
 for taking devices on the SoC out of reset or back into reset.
 Patches to use this interface on i.MX follow later in this merge
 window, and we are going to have other platforms (at least tegra
 and sirf) get converted in 3.11. This will let us get rid of
 platform specific callbacks in a number of platform independent
 device drivers.

 One of the larger platforms remaining is Samsung Exynos, and there are
 a bunch of supporting patches in this merge window for it. There was a
 patch in this branch to a early version of multiplatform conversion,
 but it ended up being reverted due to need of more bake time. The
 revert commit is part of the branch since it would have required
 rebasing multiple dependent branches and they were stable by then.

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

Pull ARM SoC multiplatform updates from Olof Johansson:
 "More multiplatform enablement for ARM platforms.  The ones converted
  in this branch are:

   - bcm2835
   - cns3xxx
   - sirf
   - nomadik
   - msx
   - spear
   - tegra
   - ux500

  We're getting close to having most of them converted!

  One of the larger platforms remaining is Samsung Exynos, and there are
  a bunch of supporting patches in this merge window for it.  There was
  a patch in this branch to a early version of multiplatform conversion,
  but it ended up being reverted due to need of more bake time.  The
  revert commit is part of the branch since it would have required
  rebasing multiple dependent branches and they were stable by then"

cc014f3e29 mmc: sdhci-s3c: remove platform dependencies
plat/regs-sdhci.h is not used anywhere but in the sdhci-s3c
driver, so it can become a local file there and all other
inclusions removed.

plat/sdhci.h is used only to define the platform devices,
and with the exception of the platform_data structure not
needed by the driver, so we can split out the platform_data
definition instead and leave the rest to platform code.

6bb27d7349 ARM: delete struct sys_timer
Now that the only field in struct sys_timer is .init, delete the struct,
and replace the machine descriptor .timer field with the initialization
function itself.

This will enable moving timer drivers into drivers/clocksource without
having to place a public prototype of each struct sys_timer object into
include/linux; the intent is to create a single of_clocksource_init()
function that determines which timer driver to initialize by scanning
the device dtree, much like the proposed irqchip_init() at:
http://www.spinics.net/lists/arm-kernel/msg203686.html

Includes mach-omap2 fixes from Igor Grinberg.

a08485d8fd ASoC: Samsung: Do not register samsung audio dma device as pdev
Previously, the ASoC 'platform' (PCM/DMA) object was instantiated via a
platform_device. This didn't represent the hardware well, since there
was no separate hardware associated with this platform_device; it was a
virtual device with sole purpose to call snd_soc_register_platform().

This change removes the platform_device completely. Each Samsung DAI now
registers the ASoC 'platform' itself. Machine drivers are adjusted for
the new 'platform' name.

308b3afb97 ARM: SAMSUNG: Add naming of s3c64xx-spi devices
Commit a5238e360b (spi: s3c64xx: move controller information into driver
data) introduced separate device names for the different subtypes of the
spi controller but forgot to set these in the relevant machines.

To fix this introduce a s3c64xx_spi_setname function and populate all
Samsung arches with the correct names. The function resides in a new
header, as the s3c64xx-spi.h contains driver platform data and should
therefore at some later point move out of the Samsung include dir.

Tested on a s3c2416-based machine.

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.)

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.

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..
