2f90b68309 drivers/rtc/rtc-vt8500.c: fix handling of data passed in struct rtc_time
tm_mon is 0..11, whereas vt8500 expects 1..12 for the month field,
causing invalid date errors for January, and causing the day field to
roll over incorrectly.

The century flag is only handled in vt8500_rtc_read_time, but not set in
vt8500_rtc_set_time.  This patch corrects the behaviour of the century
flag.

5a167f4543 Drivers: rtc: remove __dev* attributes.
CONFIG_HOTPLUG is going away as an option.  As a result, the __dev*
markings need to be removed.

This change removes the use of __devinit, __devexit_p, __devinitdata,
__devinitconst, and __devexit from these drivers.

Based on patches originally written by Bill Pemberton, but redone by me
in order to handle some of the coding style issues better, by hand.

5abe257af8 revert "rtc: recycle id when unloading a rtc driver"
Revert commit 2830a6d201.

We already perform the ida_simple_remove() in rtc_device_release(),
which is an appropriate place.  Commit 2830a6d20 ("rtc: recycle id when
unloading a rtc driver") caused the kernel to emit

	ida_remove called for id=0 which is not allocated.

warnings when rtc_device_release() tries to release an alread-released
ID.

Let's restore things to their previous state and then work out why
Vincent's kernel wasn't calling rtc_device_release() - presumably a bug
in a specific sub-driver.

18c701a9db drivers/rtc/rtc-tps65910.c: enable RTC power domain on initialization
Enabling RTC HW block depends on the default value of TPS65910 register.
In some mode, RTC block is disabled by default.(eg.  AM3517 Craneboard) In
this case, RTC_PWDN(RTC power down) bit should be cleared to enable the
RTC HW block.

This patch also works in case that RTC block is active by default, because
there is no side effect even if the bit is updated again.

Tested on AM3517 Craneboard.

c9f5c7e7a8 rtc: rtc-spear: Provide flag for no support of UIE mode
The applications can set the RTC hardware to trigger interrupts in one
of three modes:
    * AIE: Alarm interrupt
    * UIE: Update interrupt (ie: once per second)
    * PIE: Periodic interrupt (sub-second irqs)

The above defined 3 modes are to be supported in the RTC HW in form of
interrupts. The SPEAr RTC hardware does not support the later two modes.

There have been refinements in the RTC core in mainline related to
use of timer queue infrastructure to manage events in RTC. Please refer
the below mentioned patch for details:
	* RTC: Rework RTC code to use timerqueue for events
	* SHA ID: 6610e0893b

There have been provisions added to support hardware that do not have
support the UIE mode. Please refer the following patch.
	* rtc: Provide flag for rtc devices that don't support UIE
	* SHA ID: 4a649903f9

The patch makes use of the provision defined in the above patch to
update the hardware status of UIE mode.

fc9bd9022e rtc: omap: add runtime pm support
OMAP1 RTC driver is used in multiple devices like, OMAPL138 and AM33XX.
Driver currently doesn't handle any clocks, which may be right for OMAP1
architecture but in case of AM33XX, the clock/module needs to be enabled
in order to access the registers.

So convert this driver to runtime pm, which internally handles rest.

cab1458c8c rtc: omap: kicker mechanism support
OMAP RTC IP can have kicker feature.  This prevents spurious writes to
register.  To write to registers kicker lock has to be released.
Procedure to do it as follows,

1. write to kick0 register, 0x83e70b13
2. write to kick1 register, 0x95a4f1e0

Writing value other than 0x83e70b13 to kick0 enables write locking, more
details about kicker mechanism can be found in section 20.3.3.5.3 of
AM335X TRM @www.ti.com/am335x

Here id table information is added and is used to distinguish those that
require kicker handling and the ones that doesn't need it.  There are more
features in the newer IP's compared to legacy ones other than kicker,
which driver currently doesn't handle, supporting additional features
would be easier with the addition of id table.

Older IP (of OMAP1) doesn't have revision register as per TRM, so revision
register can't be relied always to find features, hence id table is being
used.

While at it, replace __raw_writeb/__raw_readb with writeb/readb; this
driver is used on ARMv7 (AM335X SoC)

2dfea3803d This is the MFD patch set for the 3.8 merge window.
We have several new drivers, most of the time coming with their sub devices
 drivers:
 
 - Austria Microsystem's AS3711
 - Nano River's viperboard
 - TI's TPS80031, AM335x TS/ADC,
 - Realtek's MMC/memstick card reader
 - Nokia's retu
 
 We also got some notable cleanups and improvements:
 
 - tps6586x got converted to IRQ domains.
 - tps65910 and tps65090 moved to the regmap IRQ API.
 - STMPE is now Device Tree aware.
 - A general twl6040 and twl-core cleanup, with moves to the regmap I/O and IRQ
   APIs and a conversion to the recently added PWM framework.
 - sta2x11 gained regmap support.
 
 Then the rest is mostly tiny cleanups and fixes, among which we have Mark's
 wm5xxx and wm8xxx patchset.

Merge tag 'mfd-3.8-1' of git://git.kernel.org/pub/scm/linux/kernel/git/sameo/mfd-2.6

Pull MFS update from Samuel Ortiz:
 "This is the MFD patch set for the 3.8 merge window.

  We have several new drivers, most of the time coming with their sub
  devices drivers:

   - Austria Microsystem's AS3711
   - Nano River's viperboard
   - TI's TPS80031, AM335x TS/ADC,
   - Realtek's MMC/memstick card reader
   - Nokia's retu

  We also got some notable cleanups and improvements:

   - tps6586x got converted to IRQ domains.
   - tps65910 and tps65090 moved to the regmap IRQ API.
   - STMPE is now Device Tree aware.
   - A general twl6040 and twl-core cleanup, with moves to the regmap
     I/O and IRQ APIs and a conversion to the recently added PWM
     framework.
   - sta2x11 gained regmap support.

  Then the rest is mostly tiny cleanups and fixes, among which we have
  Mark's wm5xxx and wm8xxx patchset."

Far amount of annoying but largely trivial conflicts.  Many due to
__devinit/exit removal, others due to one or two of the new drivers also
having come in through another tree.

1430e17844 drivers/rtc/rtc-tps65910.c: fix invalid pointer access on _remove()
The tps65910_rtc data is registered as the platform driver data in
_probe(= ).  Therefore the tps65910_rtc should be used on unregistering
the rtc device.  And device pointer should be retrieved from the
platform_device structure.

8dc0839510 rtc: kconfig: fix RTC_INTF defaults connected to RTC_CLASS
Commit 6b8029fab6 ("rtc: kconfig: remove unnecessary dependencies")
removed various 'depends on RTC_CLASS' dependencies but also removed a
few 'default RTC_CLASS' statements, which actually changed default
behavior.

This resulted in the various RTC interfaces (sysfs, proc, dev) all being
disabled by default, even when RTC_CLASS is enabled:

   # CONFIG_RTC_INTF_SYSFS is not set
   # CONFIG_RTC_INTF_PROC is not set
   # CONFIG_RTC_INTF_DEV is not set

which is different from previous behavior (all of these where enabled.)

To fix, add back the 'default RTC_CLASS' statments to each of the
RTC_INTF_* options.

I noticed this because some RTC tests started failing on my TI OMAP
platforms because /dev/rtc0 was not present anymore, even though the
driver was present and RTC_CLASS was enabled.

Commit c3b79770e5 ("rtc: m41t80: Workaround broken alarm
functionality") disabled m41t80's alarm functions.  But since those
functions were not touched, building this driver triggers these GCC
warnings:

    drivers/rtc/rtc-m41t80.c:216:12: warning: 'm41t80_rtc_alarm_irq_enable' defined but not used [-Wunused-function]
    drivers/rtc/rtc-m41t80.c:238:12: warning: 'm41t80_rtc_set_alarm' defined but not used [-Wunused-function]
    drivers/rtc/rtc-m41t80.c:308:12: warning: 'm41t80_rtc_read_alarm' defined but not used [-Wunused-function]

Remove these functions (and the commented out references to them) to
silence these warnings.  Anyone wanting to fix the alarm irq functionality
can easily find the removed code in the git log of this file or through
some web searches.
