With calling dev_pm_set_wake_irq() to set MXC_V2 RTC as wakeup source for suspend, generic wake irq mechanism will automatically enable it as wakeup source when suspend, then the suspend/resume callback which are ONLY for enabling/disabling irq wake can be removed, it simplifies the code.

The commit 1921cab1 ("rtc: rx8025: Switch to use %ptR") converted the driver to use new %p extension, but actually used wrong type of the parameter in one case. Fix a parameter to %ptR in rx8025_read_alarm(). Reported-by:

The PCF850363 has an offset correction with two modes: With mode 0, the correction is triggered once every two hours and then correction pulses are applied once per minute until the programmed correction values have been implemented. This gives a step of 4.34 ppm. With mode 1, the correction is triggered once every four minutes and then correction pulses are applied once per second up to a maximum of 60 pulses. When correction values greater than 60 pulses are used, additional correction pulses are made in the 59 th second. This gives a step of 4.069 ppm. Use the correction closest to the requested value.
