2019-04-16rtc: ds1685: use threaded interruptThomas Bogendoerfer
Handling of extended interrupts (kickstart, wake-up, ram-clear) was moved off to a work queue, but the interrupts aren't acknowledged in the interrupt handler. This leads to a deadlock, if driver is used with interrupts. To fix this we use a threaded interrupt, get rid of the work queue and do locking with just the rtc mutex lock.

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.

2019-04-04rtc: pcf85063: add offset correction supportAlexandre Belloni
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.
