I upstreamed the v2 of this series
(https://lore.kernel.org/all/20230427204540.3126234-1-dario.binacchi@amarulasolutions.com/)
that doesn't contain this change to net/main without noticing that the
DT changes in that series depend on it.

This broke the DT compilation of the stm32f746.dtsi in the net/main
tree. I don't see the stm32f7-rcc.h changes in linus/master so I'm
afraid this will break mainline too :/

What are the possible solutions? I see:
1) revert the stm32f746.dtsi changes via net/main
2) upstream the stm32f7-rcc.h changes via net/main, too
3) upstream the stm32f7-rcc.h changes via you tree, so that it hits
   mainline in the v6.4 release cycle.

I'm in favor of solution number 1. Thoughts?

Sorry for the mess,
Marc
