The em_x270_mci_setpower() and em_x270_usb_hub_init() functions
call regulator_enable(), which may return an error that must
be checked.
This changes the em_x270_usb_hub_init() function to bail out
if it fails, and changes the pxamci_platform_data->setpower
callback so that the a failed em_x270_mci_setpower call
can be propagated by the pxamci driver into the mmc core.

Pull timer core updates from Thomas Gleixner:
"The timer changes contain:
- posix timer code consolidation and fixes for odd corner cases
- sched_clock implementation moved from ARM to core code to avoid
duplication by other architectures
- alarm timer updates
- clocksource and clockevents unregistration facilities
- clocksource/events support for new hardware
- precise nanoseconds RTC readout (Xen feature)
- generic support for Xen suspend/resume oddities
- the usual lot of fixes and cleanups all over the place
The parts which touch other areas (ARM/XEN) have been coordinated with
the relevant maintainers. Though this results in an handful of
trivial to solve merge conflicts, which we preferred over nasty cross
tree merge dependencies.
The patches which have been committed in the last few days are bug
fixes plus the posix timer lot. The latter was in akpms queue and
next for quite some time; they just got forgotten and Frederic
collected them last minute."

Fix regression introduced by commit d2323cf773 ("onewire: w1-gpio: add
ext_pullup_enable pin in platform data") which added a gpio entry to the
platform data, but did not add the required initialisers to the board
files using it. Consequently, the driver would request gpio 0 at probe,
which could break other uses of the corresponding pin.
On AT91 requesting gpio 0 changes the pin muxing for PIOA0, which, for
instance, breaks SPI0 on at91sam9g20.

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.

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."

The #ifdefs around the leds-gpio device platform data are erroneous. Currently
the device is not instantiated on the centro unless CONFIG_MACH_TREO680 is
defined. This patch eliminates the #ifdefs, and uses the machine_is_* macros to
initialize the data based on which machine the code is running on and the
build-time configuration. Unused data is optimized out by the build tools if
build configuration does not enable support for both machines.
Tested on my palm treo 680, and compile-tested for all three combinations of
treo680/centro build configurations.

This patch gets the LCD working on my Palm Treo680 by adding some code that
manages the three gpios interfaced to the lcd on the Treo 680. The precise role
of each gpio in the hardware architecture is not entirely clear to me; this
patch is the result of trial-and-error and observing how the PalmOS code
initializes the lcd.
The need for this patch is not evident when Linux is loaded from PalmOS, because
at that point the lcd-related gpios have already been configured. But when
booting the kernel by other means, this patch is required unless the bootloader
has performed the necessary initialializations.

This patch fixes some code that implements a work-around to a hardware bug in
the ac97 controller on the pxa27x. A bug in the controller's warm reset
functionality requires that the mfp used by the controller as the AC97_nRESET
line be temporarily reconfigured as a generic output gpio (AF0) and manually
held high for the duration of the warm reset cycle. This is what was done in
the original code, but it was broken long ago by commit fb1bf8cd
([ARM] pxa: introduce processor specific pxa27x_assert_ac97reset())
which changed the mfp to a GPIO input instead of a high output.
The fix requires the ac97 controller to obtain the gpio via gpio_request_one(),
with arguments that configure the gpio as an output initially driven high.
Tested on a palm treo 680 machine. Reportedly, this broken code only prevents a
warm reset on hardware that lacks a pull-up on the line, which appears to be the
case for me.

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:

Merge tag 'v3.7-rc7' into next/cleanup
Merging in mainline back to next/cleanup since it has collected a few

Git doesn't auto-resolve some of them, and they're mostly noise so let's
take care of it locally.

PXA95x isn't widely used. And it adds the effort on supporting
multiple platform. So remove it.
The assumption is that nobody will miss this support. If you are
reading this text because you actually require pxa95x support on
a new kernel, we can work out a way to revert this patch or add
support to the mmp platform.

Devices that use spitz_pm.c will fail to resume
from STR (Suspend To Ram) when the charger plug is inserted
or removed when a device is in STR mode. The culprit is
a misconfigured gpio line - GPIO18. GPIO18 should be configured as a
regular GPIO input but it gets configured as an alternate function
GPIO18_RDY. And then later in postsuspend() it gets configured as
a regular GPIO18 input line.
Fix this by removing the GPIO18_RDY configuration so that GPIO18
only gets configured as a regular gpio input.

Recent changes to PXA PWM support changed the PXA27X PWM device
numbering scheme.
The linux-3.5 PXA PWM driver followed the hardware numbering scheme for
the 4 PWMs, while the linux-3.6-rc1 PXA PWM driver has adopted a linear
numbering scheme:
Address Hardware 3.5 pwm_id 3.6-rc1 pwm_id
0x40b00000 PWM0 0 0
0x40b00010 PWM2 2 1
0x40c00000 PWM1 1 2
0x40c00010 PWM3 3 3
The hx4700 backlight uses PWM1 at 0x40c00000. Consequently the pwm_id
must be changed from 1 to 2.
This patch fixes the backlight PWM device number and at the same time
moves from the legacy PWM API (pwm_id) to the new PWM API (pwm_lookup).

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,

The symbol "GPIO24_SSP1_SFRM" is defined in both mfp-pxa27x.h and
mfp-pxa25x.h. Since the macro is not actually used in the cm-x2xx.c
file, but it includes both headers, a safe workaround should be
to just undefine it from the .c file. This is a bit hacky and
the headers should be fixed to not both define it, but for now
it gets us around an annoying warning.
Without this patch, building cm_x2xx_defconfig results in:

Pull workqueue changes from Tejun Heo:
"This is workqueue updates for v3.7-rc1. A lot of activities this
round including considerable API and behavior cleanups.
* delayed_work combines a timer and a work item. The handling of the
timer part has always been a bit clunky leading to confusing
cancelation API with weird corner-case behaviors. delayed_work is
updated to use new IRQ safe timer and cancelation now works as
expected.
* Another deficiency of delayed_work was lack of the counterpart of
mod_timer() which led to cancel+queue combinations or open-coded
timer+work usages. mod_delayed_work[_on]() are added.
These two delayed_work changes make delayed_work provide interface
and behave like timer which is executed with process context.
* A work item could be executed concurrently on multiple CPUs, which
is rather unintuitive and made flush_work() behavior confusing and
half-broken under certain circumstances. This problem doesn't
exist for non-reentrant workqueues. While non-reentrancy check
isn't free, the overhead is incurred only when a work item bounces
across different CPUs and even in simulated pathological scenario
the overhead isn't too high.
All workqueues are made non-reentrant. This removes the
distinction between flush_[delayed_]work() and
flush_[delayed_]_work_sync(). The former is now as strong as the
latter and the specified work item is guaranteed to have finished
execution of any previous queueing on return.
* In addition to the various bug fixes, Lai redid and simplified CPU
hotplug handling significantly.
* Joonsoo introduced system_highpri_wq and used it during CPU
hotplug.
There are two merge commits - one to pull in IRQ safe timer from
tip/timers/core and the other to pull in CPU hotplug fixes from
wq/for-3.6-fixes as Lai's hotplug restructuring depended on them."
Fixed a number of trivial conflicts, but the more interesting conflicts
were silent ones where the deprecated interfaces had been used by new
code in the merge window, and thus didn't cause any real data conflicts.
Tejun pointed out a few of them, I fixed a couple more.
* 'for-3.7' of git://git.kernel.org/pub/scm/linux/kernel/git/tj/wq: (46 commits)

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.

This is a large branch that contains a handful of different cleanups:
- Fixing up the I/O space remapping on PCI on ARM. This is a series
from Rob Herring that restructures how all pci devices allocate I/O
space, and it's part of the work to allow multiplatform kernels.
- 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.

ARM: mach-shmobile: Add compilation support for dtbs using 'make dtbs'
+ sync to 3.6-rc3
The arm_pmu_type enumeration was initially introduced to identify
different PMU types in the system, the usual one being that on the CPU
(ARM_PMU_DEVICE_CPU). With the removal of the PMU reservation code and
the introduction of devicetree bindings for the CPU PMU, the enumeration
is no longer required.
This patch removes the enumeration and updates the various CPU PMU
platform devices so that they no longer pass an .id field referring
to identify the PMU type.

Properly register on-chip interrupt using the irqdomain logic. The
number of interrupts is taken from the devicetree node. That includes
the following changes:
- cpu_has_ipr() was converted from an inline function to a static bool
variable, so it can be set using the "marvell,intc-priority" property
inside the device node of the tree.
- IRQ_BASE was converted from a macro to a runtime variable so that it
can be initialized dynamically from the DT init code.
- irq_base() now uses pxa_irq_base and just adds an offset.
Hence, there are now no compile-time fixed values used in case of DT
initialization.

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

The EETI touchscreen asserts its IRQ line as soon as it has data in its
internal buffers. The line is automatically deasserted once all data has
been read via I2C. Hence, the driver has to monitor the GPIO line and
cannot simply rely on the interrupt handler reception.
In the current implementation of the driver, irq_to_gpio() is used to
determine the GPIO number from the i2c_client's IRQ value.
As irq_to_gpio() is not available on all platforms, this patch changes
this and makes the driver ignore the passed in IRQ. Instead, a GPIO is
added to the platform_data struct and gpio_to_irq is used to derive the
IRQ from that GPIO. If this fails, bail out. The driver is only able to
work in environments where the touchscreen GPIO can be mapped to an
IRQ.
Without this patch, building raumfeld_defconfig results in:
drivers/input/touchscreen/eeti_ts.c: In function 'eeti_ts_irq_active':
drivers/input/touchscreen/eeti_ts.c:65:2: error: implicit declaration of function 'irq_to_gpio' [-Werror=implicit-function-declaration]

This branch contains board updates, mostly for shmobile, but also a
couple for PXA.
The shmobile platforms are still in the early stages of DT enablement,
so there's a bit more updates here than we'd ideally want to see:
- regulator updates to provide some fixed regulators on several boards
- gpio support updates for multiple boards
- misc updates for recently-introduced boards armadillo800eva and kzm9g
- defconfig updates

With the changes in the random tree, IRQF_SAMPLE_RANDOM is now a
no-op; interrupt randomness is now collected unconditionally in a very
low-overhead fashion; see commit 775f4b297b. The IRQF_SAMPLE_RANDOM
flag was scheduled to be removed in 2009 on the
feature-removal-schedule, so this patch is preparation for the final
removal of this flag.

Make the OS timer registers have IOMEM like properities so they can
be passed to readl_relaxed/writel_relaxed() et.al. rather than being
straight volatile dereferences. Add linux/io.h includes where
required.

Commit e478fe4cd5 ("[ARM] pxa: merge all
eseries board code into eseries.c") removed all six files that included
eseries.h. Everything that this header provides is now either local to
eseries.c or entirely unused. It was apparently just an oversight to
keep this header. This header can safely be removed.

Basic suspend/resume is fixed by ensuring that the PGSR registers are
set correctly before sleep mode is entered. In particular four of the
active low resets need to be driven high while in sleep mode, otherwise
the unit resets itself instead of suspending. Another problem was that
the PCFR_GPROD bit is set by the HTC bootloader; this caused GPIO reset
(i.e. the reset button) to fail immediately after returning from sleep
mode.
