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.Signed-off-by: Mark Brown

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
-183000This 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 degreeSigned-off-by: Wolfgang Grandegger
