As I replied to Rob, there are no RCC STM32MP25 drivers already upstreamed.

However, in my series, the DT binding was merged even though Stephen 
made some

important remarks that needed to be taken into account.

That's why I proposed a fix to update the documentation.

To be sure, how would you like me to proceed?
