4 - compatible: can be one of the following:
5 - "st,stm32-rtc" for devices compatible with stm32(f4/f7).
6 - "st,stm32h7-rtc" for devices compatible with stm32h7.
7 - "st,stm32mp1-rtc" for devices compatible with stm32mp1.
8 - reg: address range of rtc register set.
9 - clocks: can use up to two clocks, depending on part used:
10 - "rtc_ck": RTC clock source.
11 - "pclk": RTC APB interface clock.
12 It is not present on stm32(f4/f7).
