b4d246b124 RTC: Disable CONFIG_RTC_CLASS from being built as a module
The RTC subsystem has a number of accessors that are available via
include/linux/rtc.h. However many of these interfaces are not
available for use if CONFIG_RTC_CLASS=m.

So in order to support wider use of the RTC in the kernel, I'm
removing the tristate config option for a bool, so that code can
easily be conditionalized if the RTC class is present or not.

6e57b1d6a8 RTC: Revert UIE emulation removal
Uwe pointed out that my alarm based UIE emulation is not sufficient
to replace the older timer/polling based UIE emulation on devices
where there is no alarm irq. This causes rtc devices without alarms
to return -EINVAL to UIE ioctls. The fix is to re-instate the old
timer/polling method for devices without alarm irqs.

This patch reverts the following commits:
042620a018 - Remove UIE emulation
1daeddd596 - Cleanup removed UIE emulation declaration
b5cc8ca1c9 - Remove Kconfig symbol for UIE emulation

The emulation mode will still need to be wired-in with a following
patch before it will work.

The mfd driver for MC13783 recently got support for MC13892 and was
renamed accordingly from mc13783-core to mc13xxx-core.  Do the same for
rtc-mc13783.

The only relevant change is to use platform id's to tell the platform bus
that this driver is responsible for mc13892-rtc devices, too.

fixed address and already mapped into virtual memory space.  Remove those
assumptions so the same driver can be used for similar devices that reside
at different physical addresses (e.g., TI's DA8xx/OMAP-L13x SoC's).

Also allow the possibility for the timer and alarm interrupts to use the
same IRQ.

This adds a driver for the RTC COH 901 331 found in the ST-Ericsson U300
series mobile platforms to the RTC subsystem.  It integrates to the ARM
kernel support recently added to RMKs ARM tree and will be enabled in the
U300 defconfig in due time.

d00ed3cf6e rtc: add driver for MXC's internal RTC module
This adds a driver for Freescale's MXC internal real time clock modules.

The code is taken from Freescale's BSPs, but modified to fit the current
kernel coding mechanisms.  Also, the PMIC external clock function was
removed for now to not add dead bits and keep the code as simple as
possible.

35c86bf66d rtc: Add support for RTCs on Wolfson WM831x devices
The WM831x series of PMICs contain RTC functionality. The hardware
provides a 32 bit counter incrementing at 1Hz together with a per
tick interrupt and an alarm value. For simplicity the driver chooses
to define the epoch for the counter as the Unix epoch - if required
platform data can be used in future to customise this.

When powered on from a completely cold state the RTC reports that it
has not been configured - when this happens an error is returned
when attempting to read the RTC in order to avoid use of values we
know to be invalid.

The hardware also provides security features which mean that it can
ignore attempts to set the RTC time in certain circumstances, most
notably if the RTC is written to too often. These errors are detected
by verifying the written RTC value.

3c2b9075cb rtc: add stand-alone driver for RX8025 chip
Add support for the Epson RX-8025SA/NB RTC chips.  It includes support for
alarms, periodic interrupts (1 Hz) and clock precision adjustment.

For clock precision adjustment, the SYSFS file "clock_adjust_ppb" gets
created in "/sys/class/rtc/rtcX/device".  It permits to set and get the
clock adjustment in ppb (parts per billion), e.g.:

  # echo -183000 > /sys/class/rtc/rtc0/device/clock_adjust_ppb
  # cat /sys/class/rtc/rtc0/device/clock_adjust_ppb
  -183000

This allows to compensate temperature dependent clock drifts.  According
to the RX8025 SA/NB application manual the frequency and temperature
characteristics can be approximated using the following equation:

  df = a * (ut - t)**2

  df: Frequency deviation in any temperature
  a : Coefficient = (-35 +-5) * 10**-9
  ut: Ultimate temperature in degree = +25 +-5 degree
  t : Any temperature in degree
