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.

The rtc-omap driver currently assumes that the rtc's registers are at a
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.

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.

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.

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
