2009-09-17rtc: Add support for RTCs on Wolfson WM831x devicesMark Brown1-0/+1
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.

2009-06-18rtc: add stand-alone driver for RX8025 chipWolfgang Grandegger1-0/+1
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 Signed-off-by: Wolfgang Grandegger <[email protected]> Signed-off-by: Sergei Poselenov <[email protected]> Signed-off-by: Yuri Tikhonov <[email protected]> Signed-off-by: Dmitry Rakhchev <[email protected]> Signed-off-by: Matthias Fuchs <[email protected]> Acked-by: Jean Delvare <[email protected]> Signed-off-by: Alessandro Zummo <[email protected]> Cc: David Brownell <[email protected]> Signed-off-by: Andrew Morton <[email protected]> Signed-off-by: Linus Torvalds <[email protected]>
