2f39721683 drivers/rtc/rtc-pl031.c: enable clock on all ST variants
The ST variants of the PL031 all require bit 26 in the control register
to be set before they work properly.  Discovered this when testing on
the Nomadik board where it would suprisingly just stand still.

f3ec434c69 drivers/rtc/rtc-twl.c: use static register while reading time
RTC stores time and date in several registers.  Due to the fact that
these registers can't be read instantaneously, there is a chance that
reading from counting registers gives an error of one minute, one hour,
one day, etc.

To address this issue, the RTC has hardware support to copy the RTC
counting registers to static shadowed registers.  The current
implementation does not use this feature, and in a stress test, we can
reproduce this error at a rate of around two times per 300000 readings.

Fix the implementation to ensure that the right snapshot of time is
captured.

32050017cf drivers/rtc/rtc-efi.c: fix section mismatch warning
efi_rtc_init() uses platform_driver_probe(), so there's no need to also
set efi_rtc_driver's probe member (as it won't be used anyway).  This
fixes a modpost section mismatch warning (as efi_rtc_probe() validly is
__init).

5d32c88f0b Merge branch 'akpm' (Andrew's patch-bomb)
Merge batch of fixes from Andrew Morton:
 "The simple_open() cleanup was held back while I wanted for laggards to
  merge things.

  I still need to send a few checkpoint/restore patches.  I've been
  wobbly about merging them because I'm wobbly about the overall
  prospects for success of the project.  But after speaking with Pavel
  at the LSF conference, it sounds like they're further toward
  completion than I feared - apparently davem is at the "has stopped
  complaining" stage regarding the net changes.  So I need to go back
  and re-review those patchs and their (lengthy) discussion."

Pull ARM platform updates from Russell King:
 "This covers platform stuff for platforms I have a direct interest in
  (iow, I have the hardware).  Essentially:
   - as we no longer support any other Acorn platforms other than RiscPC
     anymore, we can collect all that code into mach-rpc.
   - convert Acorn expansion card stuff to use IRQ allocation functions,
     and get rid of NO_IRQ from there.
   - cleanups to the ebsa110 platform to move some private stuff out of
     its header files.
   - large amount of SA11x0 updates:
   - conversion of private DMA implementation to DMA engine support
     (this actually gives us greater flexibility in drivers over the old
     API.)
   - re-worked ucb1x00 updates - convert to genirq, remove sa11x0
     dependencies, fix various minor issues
   - move platform specific sa11x0 framebuffer data into platform files
     in arch/arm instead of keeping this in the driver itself
   - update sa11x0 IrDA driver for DMA engine, and allow it to use DMA
     for SIR transmissions as well as FIR
   - rework sa1111 support for genirq, and irq allocation
   - fix sa1111 IRQ support so it works again
   - use sparse IRQ support

  After this, I have one more pull request remaining from my current
  set, which I think is going to be the most problematical as it
  generates 8 conflicts."

 describing the hardware in the device tree. This is only the first
 half of the changes for v3.4 because a lot of patches for this topic
 came in the last week before the merge window.

 platform changes in the same branch as the driver changes, the patches
 to the drivers are included as well.

2f6e5f9458 drivers/rtc: remove IRQF_DISABLED
Since commit e58aa3d2d0 ("genirq: run irq handlers with interrupts
disabled") we run all interrupt handlers with interrupts disabled and we
even check and yell when an interrupt handler returns with interrupts
enabled - see commit b738a50a20 ("genirq: warn when handler enables
interrupts").

So now this flag is a NOOP and can be removed.

Following changes are made as part of this change:

1. As TWL RTC supports periodic interrupt, the correct event should be
   RTC_PF instead of RTC_UF.

2. No need to initialize variable "events" to 0 & then OR it with the
   event values.  Hence fixing it.

As part of probe, before enabling RTC, RTC_CTRL register is read to check
if it is already running.  If RTC is used by kernel alone, then this read
is not required.  Even if RTC was enabled already by boot loader, setting
STOP_RTC bit again should not harm.  Hence removed unwanted read
operation.

ee6c54ca64 rtc/rtc-spear: call platform_set_drvdata() before registering rtc device
rtc_device_register() calls rtc-spear routines internally.  These
routines call dev_get_drvdata() to get struct spear_rtc_config.
Currently, platform_set_drvdata is called after rtc device is
registered.  This causes system to crash, as dev_get_drvdata returns
NULL.

For this we need to call platform_set_drvdata() before registering rtc
device.  This requires further cleanup, that leads to removal of
dev_set_drvdata on rtc->dev, which was just not required at all.

Also, we change the parameter to request_irq and pass pointer to config
instead of pointer to rtc struct.

This patch brings all above changes.

For simple modules that contain a single amba_driver without any
additional setup code then ends up being a block of duplicated
boilerplate. This patch adds a new macro, module_amba_driver(),
which replaces the module_init()/module_exit() registrations with
template functions.

4a649903f9 rtc: Provide flag for rtc devices that don't support UIE
Richard Weinberger noticed that on some RTC hardware that
doesn't support UIE mode, due to coarse granular alarms
(like 1minute resolution), the current virtualized RTC
support doesn't properly error out when UIE is enabled.

Instead the current code queues an alarm for the next second,
but it won't fire until up to a miniute later.

This patch provides a generic way to flag this sort of hardware
and fixes the issue on the mpc5121 where Richard noticed the
problem.
