Pull random subsystem patches from Ted Ts'o:
"This patch series contains a major revamp of how we collect entropy
from interrupts for /dev/random and /dev/urandom.
The goal is to addresses weaknesses discussed in the paper "Mining
your Ps and Qs: Detection of Widespread Weak Keys in Network Devices",
by Nadia Heninger, Zakir Durumeric, Eric Wustrow, J. Alex Halderman,
which will be published in the Proceedings of the 21st Usenix Security
Symposium, August 2012. (See https://factorable.net for more

When the driver detects that the clock time is invalid, it attempts to
write a sane time into the hardware. We curently assume that everything
is OK if those writes succeeded. But it is better to re-read the time
from the hardware to ensure that the new settings got there OK.

The pl031 interrupt is shared between the timer part and the clockwatch
part of the same HW block on the ux500, so mark it IRQF_SHARED on this
variant.
This patch also adds the IRQF_NO_SUSPEND flag to the rtc irq on all
variants as we don't want this pretty important IRQ to be disabled in
suspend.

Pull MFD bits from Samuel Ortiz:
"We have support for a few new drivers:
- Samsung s2mps11
- Wolfson Microelectronics wm5102 and wm5110
- Marvell 88PM800 and 88PM805
- TI twl6041
We also have our regular driver improvements:
- Device tree and IRQ domain support for STE AB8500
- Regmap and devm_* API conversion for TI tps6586x
- Device tree support for Samsung max77686
- devm_* API conversion for STE AB3100
Besides that, quite a lot of fixing and cleanup for mc13xxx, tps65910,
tps65090, da9052 and twl-core."
Fix up mostly trivial conflicts, with the exception of
drivers/usb/host/ehci-omap.c in particular, which had some
re-organization of the reset sequence (commit 1a49e2ac9651: "EHCI:
centralize controller initialization") that clashed with commit
2761a6394516 ("mfd: USB: Fix the omap-usb EHCI ULPI PHY reset fix
issues").
In particular, commit 2761a6394516 moved the usb_add_hcd() to the
*middle* of the reset sequence, which clashes fairly badly with the
reset sequence re-organization (although it could have been done inside
the new omap_ehci_init() function).
I left that part of commit 2761a6394516 just undone.

Pull arm-soc device tree description updates from Arnd Bergmann:
"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."

The tamper evident features of the RTC include the "write counter" which
is a pseudo-random number regenerated whenever we set the RTC. Since this
value is unpredictable it should provide some useful seeding to the random
number generator.
Only do this on boot since the goal is to seed the pool rather than add
useful entropy.

When suspending the system with an important RTC wake alarm active,
it is possible that the RTC alarm will expire before the system has
gone to sleep (e.g. short alarm timer, or an unusually long suspend
routine).
If this happens, the RTC alarm should trigger a wakeup event, possibly
aborting system suspend. This condition can be detected in the form
of an RTC alarm interrupt.

Requesting a threaded interrupt without a primary handler and without
IRQF_ONESHOT is dangerous, and after commit 1c6c6952 ("genirq: Reject
bogus threaded irq requests"), these requests are rejected. This causes
->probe() to fail, and the RTC driver not to be availble.
To fix, add IRQF_ONESHOT to the IRQ flags.
Tested on OMAP3730/OveroSTORM and OMAP4430/Panda board using rtcwake to
wake from system suspend multiple times.

This driver's IRQ registration is failing because the kernel now forces
IRQs to be ONESHOT if no IRQ handler is passed.

MULTI_IRQ_HANDLER and SPARSE_IRQ are now required everywhere because
mach/irqs.h and mach/entry-macros.S are gone but the symbols are
only selected for AT91SAM9, not for the NOMMU parts.
A few files now need to include linux/io.h directly, which used to
be included through other headers that have changed.
The new at91_aic_irq_priorities variable is only used with CONFIG_OF
enabled and should not be visible otherwise.

Use the devres managed resource functions in the probe routine. Also
affects the remove routine where the previously used free and release
functions are not needed.
The devm_* functions eliminate the need for manual resource releasing and
simplify error handling. Resources allocated by devm_* are freed
automatically on driver detach.

Remove RTT interrupt handling, since PIE mode interrupts are now better
emulated in generic code via an hrtimer we have no need for this, and
there is no codepath in the driver that enables these periodic interrupts
anyway.

If the rtc reports the time might be invalid due to oscillator failure,
M41T93_FLAG_OF flag must not be reset by get_time() as the read operation
doesn't make the time valid.
Without this patch, only the first get_time() reported an invalid time,
the second get_time() reported a valid time althought the reported time is
probably wrong due to oscillator failure.
Instead of resetting in get_time(), with this patch M41T93_FLAG_OF is
reset in set_time() when a valid time is to be written.

Some DS13XX devices have "trickle chargers". Its configuration register
is at different locations, the setup is the same, though. Since the
configuration is board specific, introduce a platform_data to this driver.
Tested with a DS1339 on a custom board.
