Pull ARM SoC cleanups from Arnd Bergmann:
"A large number of cleanups, all over the platforms. This is dominated
largely by the Samsung platforms (s3c, s5p, exynos) and a few of the
others moving code out of arch/arm into more appropriate subsystems.
The clocksource and irqchip drivers are now abstracted to the point
where platforms that are already cleaned up do not need to even
specify the driver they use, it can all get configured from the device
tree as we do for normal device drivers. The clocksource changes
basically touch every single platform in the process.
We further clean up the use of platform specific header files here,
with the goal of turning more of the platforms over to being
"multiplatform" enabled, which implies that they cannot expose their
headers to architecture independent code any more.
It is expected that no functional changes are part of the cleanup.
The overall reduction in total code lines is mostly the result of
removing broken and obsolete code."

SPEAr3xx architecture includes shared/multiplexed irqs for certain set
of devices. The multiplexor provides a single interrupt to parent
interrupt controller (VIC) on behalf of a group of devices.
There can be multiple groups available on SPEAr3xx variants but not
exceeding 4. The number of devices in a group can differ, further they
may share same set of status/mask registers spanning across different
bit masks. Also in some cases the group may not have enable or other
registers. This makes software little complex.
Present implementation was non-DT and had few complex data structures to
decipher banks, number of irqs supported, mask and registers involved.
This patch simplifies the overall design and convert it in to DT. It
also removes all registration from individual SoC files and bring them
in to common shirq.c.
Also updated the corresponding documentation for DT binding of shirq.

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.)

Pull ARM DMA engine updates from Russell King:
"This looks scary at first glance, but what it is is:
- a rework of the sa11x0 DMA engine driver merged during the previous
cycle, to extract a common set of helper functions for DMA engine
implementations.
- conversion of amba-pl08x.c to use these helper functions.
- addition of OMAP DMA engine driver (using these helper functions),
and conversion of some of the OMAP DMA users to use DMA engine.
Nothing in the helper functions is ARM specific, so I hope that other
implementations can consolidate some of their code by making use of
these helpers.
This has been sitting in linux-next most of the merge cycle, and has
been tested by several OMAP folk. I've tested it on sa11x0 platforms,
and given it my best shot on my broken platforms which have the
amba-pl08x controller.
The last point is the addition to feature-removal-schedule.txt, which
will have a merge conflict. Between myself and TI, we're planning to
remove the old TI DMA implementation next year."

On some platform it may happen that the input clock to keyboard may
change during suspend, thus impacting its wakeup capability.
There is no means for keyboard driver to know this frequency before
hand. Hence introduce a platform data 'suspended_rate' which indicates
the frequency during suspend at which keyboard operates.
Accordingly reprogram keyboard while going into suspend and restore
original configuration at the time of resume.

The register and irq definitions in mach/*.h for spear3xx and
spear6xx are now mostly obsolete, after the platforms have been
converted to device tree based probing and the data is now
part of the device tree files.
The misc_regs.h contents are moved into clock.c because that is
the only user, aside from the DMA_CHN_CFG that should eventually
get handled differently. Some of the contents of mach/spear.h
still remain, because they are used to set up the static map table,
timer, uart and auxdata tables, but almost everything got removed.
We might remove everything but the map table as the DT conversion
completes, but that is not a priority. I've also made sure to
make both copies of spear.h more or less identical so we can
eventually combine them.
The spear3?0.h files were only used by the spear3?0.c files, so I
merged the contents in there and removed the bits that were unused.
This is something that should still be looked at.

This patch adds a generic target for SPEAr3xx machines that can be configured
via the device-tree. Currently the following devices are supported via the
devicetree:
- VIC interrupts
- PL011 UART
- PL061 GPIO
- PL110 CLCD
- SP805 WDT
- Synopsys DW I2C
- Synopsys DW ethernet
- ST FSMC-NAND
- ST SPEAR-SMI
- ST SPEAR-KEYBOARD
- ST SPEAR-RTC
- ARASAN SDHCI-SPEAR
- SPEAR-EHCI
- SPEAR-OHCI
Other peripheral devices will follow in later patches.
This also removes IO_ADDRESS macro and creates 16 MB static mappings instead of
4K for individual peripherals. This is done to have efficient TLB lookup for any
I/O windows that are located closely together. ioremap() on this range will
return this mapping only instead of creating another.

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..

Pull #1 ARM updates from Russell King:
"This one covers stuff which Arnd is waiting for me to push, as this is
shared between both our trees and probably other trees elsewhere.
Essentially, this contains:
- AMBA primecell device initializer updates - mostly shrinking the
size of the device declarations in platform code to something more
reasonable.
- Getting rid of the NO_IRQ crap from AMBA primecell stuff.
- Nicolas' idle cleanups. This in combination with the restart
cleanups from the last merge window results in a great many
mach/system.h files being deleted."
Yay: ~80 files, ~2000 lines deleted.

We must use platform_device_add_data() instead of kbd_set_plat_data() so
let's remove it.

Several platforms create IOMEM defines for casting to 'void __iomem *',
and other platforms are incorrectly using __io() macro for the same
purpose. This creates a common definition and removes all the platform
specific versions. Rather than try to make linux/io.h and asm/io.h
assembly safe, the assembly version of IOMEM is moved into
asm/assembler.h.

Currently, the "clockevent_next_event" function only works correctly
if the timer is not running when this function is called, which is
not always the case when running with CONFIG_HIGH_RES_TIMERS.
Fix this by stopping the timer at the beginning of this function.

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.
