Hi,

This is mostly fine, even if I'm not too happy with the
s/ck_rtc/rtc_ck/.

This will never happen, you can remove that test.

This clock name has changed in datasheet between STM32F4/STM32F7 and 
STM32H7, so, I'm not really happy too... But, as there is only one clock 
on F4/F7, its name is not important for the end user. Now that pclk 
appears, we need to distinguish the two clocks, and for the end user, it 
is better if the clock names match the datasheet.

OK, will be done in V2.

Thanks for the review,
