As Nicolas and Russell pointed out, CLOCK_TICK_RATE is no more
a constant on PXA when multiple processors and platforms are
selected, change TIMER_FREQ in rtc-sa1100.c into a variable.
Since the code to decide the clock tick rate is re-used from
timer.c, introduce a common get_clock_tick_rate() for this.

The AT91CAP9 revC CPU has a few differences over the previous,
revB CPU which was distributed in small quantities only (revA was
an internal Atmel product only).
This patch adds the detection routines to recognize the different
AT91CAP9 revisions (based on the PMC subsystem version number), and
uses them to:
- activate a workaround for the external interrupts levels
(on revB CPUs)
- set the UDPHS_BYPASS bit (on revB CPUs)
- set AT91_GPBR register address to the correct offset
(0xfffffd50 on revB, 0xfffffd60 on revC)
For debugging usage, the CPU revision can be found in /proc/cpuinfo
on the 'Revision' line.
This patch is extracted from Andrew Victor's -at91 patch (2.6.27-at91.patch)
where it has been tested for the last 6 months.

This adds support for the RTC provided by the Wolfson Microelectronics
WM8350.
This driver was originally written by Graeme Gregory and Liam Girdwood,
though it has been modified since then to update it to current mainline
coding standards and for API completeness.

When fixing up invalid years rtc_read_alarm() was calling rtc_valid_tm()
as a boolean but rtc_valid_tm() returns zero on success or a negative
number if the time is not valid so the test was inverted.

As it is, all instances of ->release() for files that have ->fasync()
need to remember to evict file from fasync lists; forgetting that
creates a hole and we actually have a bunch that *does* forget.
So let's keep our lives simple - let __fput() check FASYNC in
file->f_flags and call ->fasync() there if it's been set. And lose that
crap in ->release() instances - leaving it there is still valid, but we
don't have to bother anymore.

This adds a driver for the RTC inside the TWL4030 multi-function device.
It's a fairly basic RTC, with a wake-capable alarm.
Note that many of the pre-release Overo boards now in circulation can't
effectively use this RTC, because of a wiring error that puts its TWL
chip into "secure" mode. (As in "secure yourself against tampering".)
This isn't an issue on other OMAP3 boards now supported in mainline,
such as Beagle and Labrador.

This merges branches irq/genirq, irq/sparseirq-v4, timers/hpet-percpu
and x86/uv.
The sparseirq branch is just preliminary groundwork: no sparse IRQs are
actually implemented by this tree anymore - just the new APIs are added
while keeping the old way intact as well (the new APIs map 1:1 to
irq_desc[]). The 'real' sparse IRQ support will then be a relatively
small patch ontop of this - with a v2.6.29 merge target.

Tejun's commit 7b595756ec1f49e0049a9e01a1298d53a7faaa15 made sysfs
attribute->owner unnecessary. But the field was left in the structure to
ease the merge. It's been over a year since that change and it is now
time to start killing attribute->owner along with its users - one arch at
a time!
This patch is attempt #1 to get rid of attribute->owner only for
CONFIG_X86_64 or CONFIG_X86_32 . We will deal with other arches later on
as and when possible - avr32 will be the next since that is something I
can test. Compile (make allyesconfig / make allmodconfig / custom config)
and boot tested.
akpm: the idea is that we put the declaration of sttribute.owner inside
`#ifndef CONFIG_X86'. But that proved to be too ambitious for now because
new usages kept on turning up in subsystem trees.
[akpm: remove the ifdef for now]

Teach rtc-cmos about the second bank of registers found on most modern x86
systems, giving access to 128 bytes more NVRAM.
This version only sees that extra NVRAM when both register banks are
provided as part of *one* PNP resource. Since BIOS on some systems
presents them using two IO resources, and nothing merges them, this can't
always show all the NVRAM. (We're supposed to be able to use PNP id
PNP0b01 too, but BIOS tables doesn't often seem to use that particular
option.)

Add support for M41T65 Real Time Clock chip.
The main differences I see between the M41T65 and M41T80 are that:
1) The M41T65 watchdog timer has three bits controlling resolution
(versus two for the M41T80).
2) There is no register 0x13 for controlling square-wave output.

Make the rtc framework consistent about disabling 1/second update IRQs
that may have been activated through the /dev interface, when that /dev
file is closed. (It may have closed because of coredump, etc.) This was
previously done only for emulated update IRQs ... now, do it always.
Also comment the current policy: repeating IRQs (periodic, update) that
userspace enabled will be cleanly disabled, but alarms are left alone.
Such repeating IRQs are a constant and pointless system load.
Update some RTC drivers to remove now-needless release() methods. Most
such methods just enforce that policy. The others all seem to be buggy,
and mistreat in-kernel clients of periodic or alarm IRQs.

This adds support for the Ricoh R2025S/D series of I2C RTCs, produced by
Ricoh Japan and described at:
http://www.ricoh.co.jp/LSI/product_rtc/2wire/r2025x/
This series has very minor deviations from the rest of the RS5C chips,
most of which have to do with the oscillator, which was abstracted away in
an earlier patch.

rtc-rs5c372 presently depends on I2C master mode transfers, despite the
fact that these RTCs frequently find themselves on SMBus-only adapters.
Given that the only capabilities that were checked were for I2C_FUNC_I2C,
it's assumed that most of the adapters that are currently using this
driver are fairly sane, and are able to handle SMBus emulation (though we
adjust the default capabilities to check for I2C_FUNC_SMBUS_EMUL anyways,
which is the vast majority of them. The adapters that don't have their
own ->smbus_xfer() fall back on the ->master_xfer() through the emulated
transfer).
The special case is iop3xx, which has more than its fair share of hacks
within this driver, it remains untested -- though also claims to support
emulated SMBus accesses. The corner case there is rs5c_get_regs() which
uses access mode #3 for transferring the register state, while we use mode
#1 for SMBus.
