Wolfram Sang 59bfee6e06 i2c: Remove obsolete cleanup for clientdata
A few new i2c-drivers came into the kernel which clear the clientdata-pointer
on exit. This is obsolete meanwhile, so fix it and hope the word will spread.

Vladimir Zapolskiy f501ed524b rtc: s3c: balance state changes of wakeup flag
This change resolves a problem about unbalanced calls of
enable_irq_wakeup() and disable_irq_wakeup() for alarm interrupt.

Commit b485fe5ea ("rtc/m41t80: use rtc_valid_tm() to check returned tm")
added rtc_valid_tm to m41t80_rtc_read_alarm() but it was wrong while the
t->time does not contain complete date/time.

This patch also fixes a warning:

Mike Frysinger b6de860651 rtc-bfin: fix state restoration when resuming
Much (but not all) of the RTC state is kept in the RTC peripheral which
has its own power domain.  Periodically (1 HZ), that state is synced from
one power domain to the other (peripheral->core).  When we are resuming,
we need to wait for the sync to occur so that we don't get a mismatch of
reading undefined state in the rest of the driver.

Further, once the externally maintained bits have been synced back into
the core, we then need to restore the bits maintained in the core.  In our
particular case, that is just the write completion interrupt bit.

If we don't do any of this, working with the RTC causes ~5 second delays
from time to time after waking up due to the write completion interrupt
never firing.

Wan ZongShun 23e53be94a rtc/nuc900: modify enable/disable IRQs and driver data setting location
This patch does two modifications:

(1) Adjust enable/disable IRQs location,enable it after rtc
    registration and disable it prior to unregistration.

(2) Put 'platform_set_drvdata(pdev, nuc900_rtc)' in front of rtc
    registration still be safety, though there is no need to do this, when
    I move enable irq after rtc registration, I think still put
    'platform_set_drvdata' before rtc registration that would be a good
    habit.

- remove clearing of AF bit after reading rtc/alarm control register:

advantage of 'rtc_valid_tm(tm)' to check 'rtc_time *tm' value validity, it
make sure the 'tm->tm_year' is larger than 70,so if '70< tm_year < 100',
the '(settm->tm_year - 100)' will be negative.  ' Setting the negative
value to hardware register will be invalid, so I add the 'if' condition to
make sure set a valid value to register.

Atul Dahiya 16f4efe7bf rtc: rtc-s3c: Add extra option to include RTC for Samsung SoCs
This patch adds HAVE_S3C_RTC to control inclusion of RTC driver for Samsung
SoCs. This option will help to include the driver only for the necessary
machines and not for any given arch.

Atul Dahiya 2f3478f657 rtc: rtc-s3c: Updates driver for S3C64XX and newer SoCs
This Patch does followings.
1) Enables support for alarm and time tick pending register
   for periodic interrupt generation.
2) Changes writeb to writew beacuse the macro S3C64XX_RTCCON_TICEN
   (Tick Timer Enable) is 9th bit of register.
3) Changes writeb to writel as max_user_freq used in s3c64xx is 32768 and
   requires 15 bits to update the Tick Count Register.

Rudolf Marek 2884fce165 drivers/rtc/rtc-rx8581.c: fix setdatetime
Fix the logic while writing new date/time to the chip.  The driver
incorrectly wrote back register values to different registers and even
with wrong mask.  The patch adds clearing of the VLF register, which
should be cleared if all date/time values are set.

Russell King 2c39c9e149 ARM: Fix section build warnings for AMBA drivers
Found in the Versatile build:

WARNING: drivers/built-in.o(.data+0x14c): Section mismatch in reference from the variable pl061_gpio_driver to the (unknown reference) .init.data:(unknown)
The variable pl061_gpio_driver references
the (unknown reference) __initdata (unknown)

WARNING: drivers/built-in.o(.data+0x40f8): Section mismatch in reference from the variable pl011_driver to the (unknown reference) .init.data:(unknown)
The variable pl011_driver references
the (unknown reference) __initdata (unknown)

WARNING: drivers/built-in.o(.data+0x5ab4): Section mismatch in reference from the variable pl031_driver to the (unknown reference) .init.data:(unknown)
The variable pl031_driver references
the (unknown reference) __initdata (unknown)

Basically, amba_id structures must not be __initdata.  Also fix:

WARNING: drivers/built-in.o(.data+0x138): Section mismatch in reference from the variable pl061_gpio_driver to the function .init.text:pl061_probe()
The variable pl061_gpio_driver references
the function __init pl061_probe()

which is an incorrectly annotated probe function.  Fix it to reflect
the other AMBA bus probe functions by removing the __init attributation.

Joakim Tjernlund 96fc3a45ea rtc: fix ds1388 time corruption
The ds1307 driver misreads the ds1388 registers when checking for 12 or 24
hour mode.  Instead of checking the hour register it reads the minute
register.  Therefore the driver thinks minutes >= 40 has the 12HR bit set
and resets the minute register by zeroing the high bits.  This results in
minutes are reset to 0-9, jumping back in time 40 or 50 minutes.  The time
jump is also written back to the RTC.
