The reason for this is that the Debug Unit Chip ID Register has changed between
Engineering Sample and definitive revision of the SoC. Changing the check of
cidr to socid will address the problem. We do not integrate this check to the
list just above because we also have to make sure that the extended id is
disregarded.

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.)

12250d843e Merge branch 'i2c-embedded/for-next' of git://git.pengutronix.de/git/wsa/linux
Pull i2c-embedded changes from Wolfram Sang:
 "The changes for i2c-embedded include:

   - massive rework of the omap driver
   - massive rework of the at91 driver.  In fact, the old driver gets
     removed; I am okay with this approach since the old driver was
     depending on BROKEN and its limitations made it practically
     unusable, so people used bitbanging instead.  But even if there are
     users, there is no platform_data or module parameter which would
     need to be converted.  It is just another driver doing I2C
     transfers, just way better.  Modifications of arch/arm/at91 related
     files have proper acks from the maintainer.
   - new driver for R-Car I2C
   - devicetree and generic_clock conversions and fixes
   - usual driver fixes and changes.

  The rework patches have come a long way and lots of people have been
  involved in creating/testing them.  Most patches have been in
  linux-next at least since 3.6-rc5.  A few have been added in the last
  week, I have to admit.

  An unexpected (but welcome :)) peak in private life is the cause for
  that.  The "late" patches shouldn't cause any merge conflicts and I
  will have a special eye on them during the stabilization phase.  This
  is an exception and I want to have the patches in place properly in
  time again for the next kernels."

ac09281a02 ARM: at91: skip at91_io_desc definition for NOMMU
On NOMMU systems, we do cannot remap the MMIO space, so the
definition of at91_io_desc is unused.

Without this patch, building at91x40_defconfig results in:

arch/arm/mach-at91/setup.c:90:24: warning: 'at91_io_desc' defined but not used [-Wunused-variable]

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.

2. Interrupt driven I/O as opposed to polling/busy waiting.
3. Support for _one_ repeated start (Sr) condition, which is enough
   for most real-world applications including all SMBus transfer types.

19e4ab54e7 Merge branch 'for-arm-soc' of git://git.kernel.org/pub/scm/linux/kernel/git/cooloney/linux-leds into next/drivers
From Bryan Wu <bryan.wu@canonical.com>:

Based on Linus Walleij's ARM LED consolidation work, this patchset introduce a
new generic led trigger for CPU not only for ARM but also for others.

For enabling CPU idle event, CPU arch code should call ledtrig_cpu() stub to
trigger idle start or idle end event.

These patches convert old style LED driver in arch/arm to gpio_led or new led
driver interface. Against 3.5 release and build successfully for all the machines.

Test ledtrig-cpu driver on OMAP4 Panda board.

v9 --> v10
 * fix compiling issue on versatile_defconfig reported by Russell King
 * rebase to 3.5 kernel and move patches to new git tree

v8 --> v9:
 * use mutex to replace rw_sema pointed out by Tim Gardner
 * add a new struct led_trigger_cpu
 * add lock_is_inited to record mutex lock initialization

v6 --> v7:
 * add a patch to unify the led-trigger name
 * fix some typo pointed
 * use BUG_ON to detect CPU numbers during building stage

v5 --> v6:
 * replace  __get_cpu_var() to per_cpu()
 * remove smp_processor_id() which is wrong with for_each_possible_cpu()
 * test on real OMAP4 Panda board
 * add comments about CPU hotplug in the CPU LED trigger driver

v4 --> v5:
 * rebase all the patches on top of latest linux-next
 * replace on_each_cpu() with for_each_possible_cpu()
 * add some description of ledtrig_cpu() API
 * remove old leds code from driver nwflash.c, which should use a new led trigger then
 * this trigger driver can be built as module now

v3 --> v4:
 * fix a typo pointed by Jochen Friedrich
 * fix some building errors
 * add Reviewed-by and Tested-by into patch log

v2 --> v3:
 * almost rewrote the whole ledtrig-cpu driver, which is more simple
 * every CPU will have a per-CPU trigger
 * cpu trigger can be assigned to any leds
 * fix a lockdep issue in led-trigger common code
 * other fix according to review

v1 --> v2:
 * remove select operations in Kconfig of every machines
 * add back supporting of led in core module of mach-integrator
 * solidate name scheme in ledtrig-cpu.c
 * add comments of CPU_LED_* cpu led events
 * fold patches of RealView and Versatile together
 * add machine_is_ check during assabet led driver init
 * add some Acked-by in patch logs
 * remove code for simpad machine in machine-sa11000, since Jochen Friedrich
   introduced gpiolib and gpio-led driver for simpad
 * on Assabet and Netwinder machine, LED operations is reversed like:
   setting bit means turn off leds
   clearing bit means turn on leds
 * add a new function to read CM_CTRL register for led driver

* 'for-arm-soc' of git://git.kernel.org/pub/scm/linux/kernel/git/cooloney/linux-leds:
  ARM: use new LEDS CPU trigger stub to replace old one

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.

we need some dedicated callbacks for AIC5.
Power management is also concerned by these changes. On suspend, we can't get
the whole interrupt mask register as before, we have to read this register 128
times. To reduce this overhead, a snapshot of the whole IMR is maintained.

Commit 82c583e3ae ("AT91RM9200 hardware

arch/arm/mach-at91/include/mach/at91_ssc.h. (These files were called
at91rm9200_spi.h and at91rm9200_ssc.h then.) That commit was added in
the v2.6.18 development cycle.

Nothing includes them now and nothing uses the named constants they
provide. (There's no way these named constants could be used unless
these files were included somehow.) It actually seems these two headers
have never been used since they were added to the tree. They can safely
be removed.

 Loads of changes here, and we just narrowly added more lines than we
 added:
  622 files changed, 28356 insertions(+), 26059 deletions(-)
 
 But, good news is that there is a number of subsystems that moved out of
 the staging tree, to their respective "real" portions of the kernel.
 
 Code that moved out was:
 	- iio core code
 	- mei driver
 	- vme core and bridge drivers
 
 There was one broken network driver that moved into staging as a step
 before it is removed from the tree (pc300), and there was a few new
 drivers added to the tree:
 	- new iio drivers
 	- gdm72xx wimax USB driver
 	- ipack subsystem and 2 drivers
 
 All of the movements around have acks from the various subsystem
 maintainers, and all of this has been in the linux-next tree for a
 while.

9f639269ed arm-soc: support for new SoCs
Three new system-on-chip models are supported: the st-ericsson u9540
 in ux500, the sam9n12 in at91 and the emma ev2 in shmobile.
 
 Emma is a little bit special because it is completely unrelated to
 the classic shmobile models, but the new Renesas rmobile SoCs are a
 combination of things from both Emma and shmobile, so it was decided to
 have them all live in one directory.
 
 This also contains updates to existing shmobile soc code as well as some
 related board changes due to dependencies.

Pull support for new arm SoCs from Olof Johansson:
 "Three new system-on-chip models are supported: the st-ericsson u9540
  in ux500, the sam9n12 in at91 and the emma ev2 in shmobile.

  Emma is a little bit special because it is completely unrelated to the
  classic shmobile models, but the new Renesas rmobile SoCs are a
  combination of things from both Emma and shmobile, so it was decided
  to have them all live in one directory.

  This also contains updates to existing shmobile soc code as well as
  some related board changes due to dependencies."

b324c67d48 arm-soc: device tree conversions, part 1
The spear3xx, lpc32xx, shmobile and mmp platforms are joining the game of
 booting using device trees, which is a great step forward for them. at91
 and spear have pretty much completed this process with a huge amount of
 work being put into at91. The other platforms are continuing the process.
 
 We finally start to see the payback on this investment, as new machines
 are getting supported purely by adding a .dts source file that can be
 completely independent of the kernel source.

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.

The maxburst/chunk size was taken from the private slave DMA data structure.
Use the common API provided by DMA_SLAVE_CONFIG to setup src/dst maxburst
values.
The ctrla field is not needed anymore in the slave private structure nor the
header constants that were located in an architecture specific directory.
The at91sam9g45_devices.c file that was using this platform data is also
modified to remove this now useless data.

* Pass the physical base-address via platform-resources to the driver.
* Convert at91_ether.c driver to perform an ioremap().
* Ethernet PHY detection needs to be performed during the driver

1ac02d7958 ARM: fix __io macro for PCMCIA
With commit c334bc1 (ARM: make mach/io.h include optional), PCMCIA was
broken. PCMCIA depends on __io() returning a valid i/o address, and most
ARM platforms require IO_SPACE_LIMIT be set to 0xffffffff for PCMCIA. This
needs a better fix with a fixed i/o address mapping, but for now we just
restore things to the previous behavior.

This fixes at91, omap1, pxa and sa11xx. pxa needs io.h if PCI is enabled,
but PCMCIA is not. sa11xx already has IO_SPACE_LIMIT set to 0xffffffff,
so it doesn't need an io.h.

This does a sweeping change fixing up all the missing system_misc.h and
system_info.h includes from the system.h split-up change. These were the
ones I came across when building all defconfigs in arch/arm/configs, there
might be more but they lack adequate build coverage to be easily caught.

I'm expecting to get a lot of these piecemeal by each maintainer, so we
might just as well do one sweeping change to get them all at once.

Merge tag 'split-asm_system_h-for-linus-20120328' of git://git.kernel.org/pub/scm/linux/kernel/git/dhowells/linux-asm_system

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..

beeaa103ee dmaengine: at_hdmac: add slave config operation
This patch introduces DMA_SLAVE_CONFIG to at_hdmac Atmel DMA driver.

It is needed to fix a regression in the use of atmel-mci.c driver on Atmel
AT91 platforms brouth by e2b35f3:
"dmaengine/dw_dmac: Fix dw_dmac user drivers to adapt to slave_config changes"

We remove some parts of the private structure "at_dma_slave" and use the
information provided by "struct dma_slave_config": source/destination
peripheral registers and access width.

AT_DMA_SLAVE_WIDTH_* values used previously are not needed anymore as we
now use the standard ones. Although some conversion functions are needed to
match register expected values.

Some AT91 sub-architecture specific files are slightly touched by this patch
but it cannot be split because it can break compilation.

8014d6f4dd ARM: at91: AIC and GPIO IRQ device tree initialization
Both AIC and GPIO controllers are now using the standard of_irq_init()
function to initialize IRQs in case of DT use.
The DT specific initialization functions are now separated from the
non-DT case and are now using "linear" irq domains.
The .map() irqdomain operation is responsible for positioning the IRQ
handlers. In AIC case, the Linux IRQ number is directly programmed in
the hardware to avoid an additional reverse mapping operation.
The AIC position its irq domain as the "default" irq domain.

For DT case, the priority is not yet filled in the SMR. It will be the
subject of another patch.

00482a4078 ARM: at91: implement the standby function for pm/cpuidle
This patch groups the self-refresh on/cpu_do_idle/self-refresh off into
a single 'standby' function.

The standby routine for rm9200 has been turned into an asm routine to have
a better control of the self refresh and to prevent a memory access when
running this code.

Draining the write buffer is done automatically when switching for the self
refresh on sam9, so the instruction is added to the rm9200 only.

Then it is safe to invoke cpu_do_idle for this platform. As all the

and replace its invokation by cpu_do_idle.

14f991a730 ARM: at91: Fix at91sam9g45 and at91cap9 reset
As on the other sam9 we need to cleanly shutdown the DDRAM before rebooting.

On those SoC the SDRAM/DDRAM controller is different. So, the assembly code
ends up being not cleanly combined with previous at91sam9_alt_restart function.

3e90772f76 ARM: at91: fix at91rm9200 soc subtype handling
Currently setting it to PQFP changes subtype to BGA as subtypes are
swapped in at91rm9200_set_type().

Wrong subtype causes GPIO bank D not to work at all.

After this fix, subtype is still set as unknown. But board code should
fill it in with proper value. Another information is thus printed.

Bug discovery and first implementation made by Veli-Pekka Peltola.

f88b8979d2 ARM: restart: remove the now empty arch_reset()
Remove the now empty arch_reset() from all the mach/system.h includes,
and remove its callsite.  Remove arm_machine_restart() as this function
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.

1b2073e778 ARM: restart: at91: use new restart hook
Rather than using a private function pointer, use the existing
arm_pm_restart function pointer instead.  We no longer need to enable
the I-cache in at91sam9_alt_reset() as the caches will now be on when
this function is called.

Update the function names to use the 'restart' terminology rather than
the 'reboot' terminology.
