Subject[PATCH v3 0/4] Introduce STM32MP1 RTC
Date
This series introduces STM32MP1 RTC.
On STM32MP1:
- two clocks are needed, plck and rtc_ck;
- to wakeup the system, a wakeup alarm interrupt is needed;
- some registers or bits have moved, but the operation is the same;
- the Backup Domain Protection (DBP) is not managed by RTC driver.

---
Changes in v3:
* Move cleanup changes in a separate patch
* Replace regs and evts by pointers to ensure no copy is made
* Set all registers offset as u16 instead of u8 and u16
* Fix Kbuild smatch warning:
drivers/rtc/rtc-stm32.c:827 stm32_rtc_probe()
warn: always true condition '(regs.verr != ~0) => (0-u16max != (-1))'

Changes in v2:
* One compatible per line in bindings file
* Remove unnecessary comment under rtc_ck as this clock is required for all
* Remove interrupts-extended and add stm32mp1 rtc alarm wakeup interrupt in
interrupts property description
