6d5aefb8ea WorkQueue: Fix up arch-specific work items where possible
Fix up arch-specific work items where possible to use the new work_struct and
delayed_work structs.

Three places that enqueue bits of their stack and then return have been marked

afe4b25e7d [ARM] 3881/4: xscale: clean up cp0/cp1 handling
XScale cores either have a DSP coprocessor (which contains a single
40 bit accumulator register), or an iWMMXt coprocessor (which contains
eight 64 bit registers.)

Because of the small amount of state in the DSP coprocessor, access to
the DSP coprocessor (CP0) is always enabled, and DSP context switching
is done unconditionally on every task switch.  Access to the iWMMXt
coprocessor (CP0/CP1) is enabled only when an iWMMXt instruction is
first issued, and iWMMXt context switching is done lazily.

CONFIG_IWMMXT is supposed to mean 'the cpu we will be running on will
have iWMMXt support', but boards are supposed to select this config
symbol by hand, and at least one pxa27x board doesn't get this right,
so on that board, proc-xscale.S will incorrectly assume that we have a
DSP coprocessor, enable CP0 on boot, and we will then only save the
first iWMMXt register (wR0) on context switches, which is Bad.

This patch redefines CONFIG_IWMMXT as 'the cpu we will be running on
might have iWMMXt support, and we will enable iWMMXt context switching
if it does.'  This means that with this patch, running a CONFIG_IWMMXT=n
kernel on an iWMMXt-capable CPU will no longer potentially corrupt iWMMXt
state over context switches, and running a CONFIG_IWMMXT=y kernel on a
non-iWMMXt capable CPU will still do DSP context save/restore.

These changes should make iWMMXt work on PXA3xx, and as a side effect,
enable proper acc0 save/restore on non-iWMMXt capable xsc3 cores such
as IOP13xx and IXP23xx (which will not have CONFIG_CPU_XSCALE defined),
as well as setting and using HWCAP_IWMMXT properly.

46ec0ce8ce [ARM] 3940/1: don't reset PXA2xx clock counter
Don't reset OSCR to zero as this prevents us from having a contiguous
time source. The value returned by sched_clock() is reset to zero in the
middle of the boot process otherwise, making CONFIG_PRINTK_TIME rather
messed up.

d14b272bc6 [ARM] 3848/1: pxafb: Add option of fixing video modes and spitz QVGA mode support
Add the ability to have pxafb use only certain fixed video modes
(selected on a per platform basis). This is useful on production
hardware such as the Zaurus cxx00 models where the valid modes are
known in advance and any other modes could result in hardware damage.

Following this, add support for the cxx00 QVGA mode. Mode information
is passed to the lcd_power call to allowing the panel drivers to
configure the display hardware accordingly (corgi_lcd already contains
the functionality for the cxx00 panel).

This mirrors the setup already used by w100fb.

b2bbb20b37 USB: pxa2xx_udc understands GPIO based VBUS sensing
This updates the PXA 25x UDC board-independent infrastructure for VBUS sensing
and the D+ pullup.  The original code evolved from rather bizarre support on
Intel's "Lubbock" reference hardware, so that on more sensible hardware it
doesn't work as well as it could/should.

The change is just to teach the UDC driver how to use built-in PXA GPIO pins
directly.  This reduces the amount of board-specfic object code needed, and
enables the use of a VBUS sensing IRQ on boards (like Gumstix) that have one.
With VBUS sensing, the UDC is unclocked until a host is actually connected.

Patch from David Brownell

ARM genirq cleanups/updates:

    - Start switching platforms to newer APIs
        * use "irq_chip" name, not "irqchip"
        * providing irq_chip.name

    - Show irq_chip.name in /proc/interrupts, like on x86.

This update a bit more than half of the ARM code.  The irq_chip.name
values were chosen to match docs (if I have them) or be otherwise
obvious ("FPGA", "CPLD", or matching the code).

9ded96f24c [PATCH] IRQ type flags
Some ARM platforms have the ability to program the interrupt controller to
detect various interrupt edges and/or levels.  For some platforms, this is
critical to setup correctly, particularly those which the setting is dependent
on the device.

Currently, ARM drivers do (eg) the following:

	err = request_irq(irq, ...);

	set_irq_type(irq, IRQT_RISING);

However, if the interrupt has previously been programmed to be level sensitive
(for whatever reason) then this will cause an interrupt storm.

Hence, if we combine set_irq_type() with request_irq(), we can then safely set
the type prior to unmasking the interrupt.  The unfortunate problem is that in
order to support this, these flags need to be visible outside of the ARM
architecture - drivers such as smc91x need these flags and they're
cross-architecture.

Finally, the SA_TRIGGER_* flag passed to request_irq() should reflect the
property that the device would like.  The IRQ controller code should do its
best to select the most appropriate supported mode.

1ee9530a71 [ARM] 3201/1: PXA27x: Prevent hangup during resume due to inadvertedly enabling MBREQ (replaces: 3198/1)
Patch from Lothar Wassmann

The patch makes sure, that the ouptut functions of pins are restored
before restoring the Alternat Function settings, preventing pins from
being intermediately configured for undefined or unwanted alternate
functions.

Here is the original comment:
I've got a PXA270 system that uses GPIO80 as nCS4. This system did
hang on resume. Digging into the problem I found that the processor
stalled immediately when restoring the GAFR2_U register which restored
the alternate function for GPIO80. Since the GPDR registers were
restored after the GAFR registers, the offending GPIO was configured
as input at this point.
Thus the alternate function that was in effect after restoring the
GAFR was in fact the input function "MBREQ" instead of the output
function "nCS4". The "PXA27x Processor Family Developer's Manual"
(Footnote in Table 6-1 on page 6-3) states that:
"The MBREQ alternate function must not be enabled until the PSSR[RDH]
bit field is cleared. For more details, see Table 3-15, "PSSR Bit
Definitions" on page 3-71."

There is another note in the Developer's Manual (chapter 24.4.2
"GPIO operation as Alternate Function" on page 24-4)
stating that:
"Configuring a GPIO for an alternate function that is not defined for
it causes unpredictable results."

Since some GPIOs have no input function defined, and to prevent
inadvertedly programming the MBREQ function on some pin, the GAFR
registers should be restored after the GPDR registers have been
restored.

Additional provisions have to be made when the MBREQ function is
actually required. The corresponding GAFR bits should not be restored
with the regular GAFR restore, but must be set only after the PSSR
bits have been cleared.

bd5d080ab9 [ARM] 3160/1: SharpSL: Add driver for Akita specific GPIOs
Patch from Richard Purdie

Add a driver for the extra GPIOs found on the Sharp SL-C1000 (Akita).
These GPIOs are found on a Maxim MAX7310 I2C i/o expander chip. A
generic GPIO driver for the MAX7310 was attempted but this mini
driver is a much simpler and much more effective solution avoiding
several issues and complexity the generic driver had (as discussed
on LKML).

The platform device is required so the device parent can be set
correctly which ensures the device is one of the last to suspend
and first to resume. Whilst the i2c suspend/resume calls can be
influenced, nothing guarantees this is easlier/later than the
subsystems the gpios are used on which are all independent of i2c
(sound, irda, video/backlight etc.).

078abcf95c [ARM] 3096/1: Add SharpSL Zaurus power and battery management core driver
Patch from Richard Purdie

This patch adds a power and battery management core driver which with
the addition of the right device files, supports the c7x0 and cxx00
series of Sharp Zaurus handhelds.

The driver is complex for several reasons. Battery charging is manually
monitored and controlled. When suspended, the device needs to
periodically partially resume, check the charging status and then
re-suspend. It does without bothering the higher linux layers as
a full resume and re-suspend is unnecessary. The code is carefully
written to avoid interrupts or calling code outside the module under
these circumstances. It also vets the various wake up sources and
monitors the device's power situation.

Hooks to limit the backlight intensity and to notify the battery
monitoring code of backlight events are connected/added as the
backlight is one of the biggest users of power on the device.

74ec71e161 [ARM] 3087/1: PXA2xx flash platform device conversion
Patch from Todd Poynor

Add platform devices for flash to Lubbock and Mainstone board files.
Once in place, the two existing mtd map drivers for the boards will be
converted to use a single pxa2xx map driver in the linux-mtd tree.
Take 4: flash_platform_data .map_name vs. .name cleaned up, resync with
merged irda patch context.

Patch from David Brownell

Lubbock updates:

  * Provide an address for the SMC91x chip that doesn't generate
    a boot-time warning (matching the EEPROM).

  * Update MMC support to (a) detect card insert/remove, and
    (b) report the readonly switch setting for SD cards.

Previously, MMC/SD cards had to be present at boot time else they
couldn't be detected.

4e57b68178 [PATCH] fix missing includes
I recently picked up my older work to remove unnecessary #includes of
sched.h, starting from a patch by Dave Jones to not include sched.h
from module.h. This reduces the number of indirect includes of sched.h
by ~300. Another ~400 pointless direct includes can be removed after
this disentangling (patch to follow later).
However, quite a few indirect includes need to be fixed up for this.

In order to feed the patches through -mm with as little disturbance as
possible, I've split out the fixes I accumulated up to now (complete for
i386 and x86_64, more archs to follow later) and post them before the real
patch.  This way this large part of the patch is kept simple with only
adding #includes, and all hunks are independent of each other.  So if any
hunk rejects or gets in the way of other patches, just drop it.  My scripts
will pick it up again in the next round.

9480e307cd [PATCH] DRIVER MODEL: Get rid of the obsolete tri-level suspend/resume callbacks
In PM v1, all devices were called at SUSPEND_DISABLE level.  Then
all devices were called at SUSPEND_SAVE_STATE level, and finally
SUSPEND_POWER_DOWN level.  However, with PM v2, to maintain
compatibility for platform devices, I arranged for the PM v2
suspend/resume callbacks to call the old PM v1 suspend/resume
callbacks three times with each level in order so that existing
drivers continued to work.

Since this is obsolete infrastructure which is no longer necessary,
we can remove it.  Here's an (untested) patch to do exactly that.

Patch from Todd Poynor

Add symbols for PXA2xx PWRMODE register M field that selects low-power
mode, replace unadorned constants.  Honor power mode parameter of
pxa_cpu_suspend(mode), no longer force to 3 (sleep).  Full Deep Sleep
low-power mode support for PXA27x is pending generic PM interfaces to
select more than 2 suspend-to-RAM-style power modes, but this is
expected soon. This can be hardcoded in the meantime by replacing the
pxa_cpu_suspend() parameter value.  From David Burrage and Todd Poynor.
Try #2 removes one of the register copies and moves the code to save the
pxa_cpu_suspend parameter to immediately surround the call that requires
the parameter value be preserved.

Sharp's newer range of Zaurus clamshell handhelds, the cxx00's are similar to
the c7x0 series yet different.  This patch series abstracts the differences
and generates a set of common drivers that support both series of devices.  It
then adds machine support for Spitz (SL-C3000) and Borzoi (SL-C3100).  Hooks
for Akita (SL-C1000) differences are also added.  The I2C driver for its IO
expander is the only missing piece.

This patch:

Separate out the Sharp Zaurus c7x0 series specific code from corgi_ssp.c so
that other models such as the cxx00's can share it.  Create sharpsl.h which
will be used to abstract machine/model specifics.

This enables the driver to be used by the Zaurus cxx00 series.

8775420d2f [PATCH] ARM: 2691/1: PXA27x sleep fixes take 2
Patch from Todd Poynor

PXA27x sleep fixes:
* set additional sleep/wakeup registers for Mainstone boards.
* move CKEN=0 to pxa25x-specific code; that value is harmful on pxa27x.
* save/restore additional registers, including some found necessary for
C5 processors and/or newer blob versions.
* enable future support of additional sleep modes for PXA27x (eg,
standby, deep sleep).
* split off cpu-specific sleep processing between pxa27x and pxa25x into
separate files (partly in preparation for additional sleep modes).
Includes fixes from David Burrage.

Initial git repository build. I'm not bothering with the full history,
even though we have it. We can create a separate "historical" git
archive of that later if we want to, and in the meantime it's about
3.2GB when imported into git - space that would just make the early
git days unnecessarily complicated, when we don't have a lot of good
infrastructure for it.

Let it rip!
