      "message": "rtc: add stand-alone driver for RX8025 chip\n\nAdd support for the Epson RX-8025SA/NB RTC chips.  It includes support for\nalarms, periodic interrupts (1 Hz) and clock precision adjustment.\n\nFor clock precision adjustment, the SYSFS file \"clock_adjust_ppb\" gets\ncreated in \"/sys/class/rtc/rtcX/device\".  It permits to set and get the\nclock adjustment in ppb (parts per billion), e.g.:\n\n  # echo -183000 \u003e /sys/class/rtc/rtc0/device/clock_adjust_ppb\n  # cat /sys/class/rtc/rtc0/device/clock_adjust_ppb\n  -183000\n\nThis allows to compensate temperature dependent clock drifts.  According\nto the RX8025 SA/NB application manual the frequency and temperature\ncharacteristics can be approximated using the following equation:\n\n  df \u003d a * (ut - t)**2\n\n  df: Frequency deviation in any temperature\n  a : Coefficient \u003d (-35 +-5) * 10**-9\n  ut: Ultimate temperature in degree \u003d +25 +-5 degree\n  t : Any temperature in degree\n\nSigned-off-by: Wolfgang Grandegger \u003cwg@grandegger.com\u003e\nSigned-off-by: Sergei Poselenov \u003csposelenov@emcraft.com\u003e\nSigned-off-by: Yuri Tikhonov \u003cyur@emcraft.com\u003e\nSigned-off-by: Dmitry Rakhchev \u003crda@emcraft.com\u003e\nSigned-off-by: Matthias Fuchs \u003cmatthias.fuchs@esd.eu\u003e\nAcked-by: Jean Delvare \u003ckhali@linux-fr.org\u003e\nSigned-off-by: Alessandro Zummo \u003ca.zummo@towertech.it\u003e\nCc: David Brownell \u003cdavid-b@pacbell.net\u003e\nSigned-off-by: Andrew Morton \u003cakpm@linux-foundation.org\u003e\nSigned-off-by: Linus Torvalds \u003ctorvalds@linux-foundation.org\u003e\n"
