It is required only on stm32h7.
- interrupt-parent: phandle for the interrupt controller.
- interrupts: rtc alarm interrupt.
-- st,syscfg: phandle for pwrcfg, mandatory to disable/enable backup domain
- (RTC registers) write protection.
+- st,syscfg: phandle/offset/mask triplet. The phandle to pwrcfg used to
+ access control register at offset, and change the dbp (Disable Backup
+ Protection) bit represented by the mask, mandatory to disable/enable backup
+ domain (RTC registers) write protection.
Optional properties (to override default rtc_ck parent clock):
- assigned-clocks: reference to the rtc_ck clock entry.

interrupts = <17 1>;
- st,syscfg = <&pwrcfg>;
