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

DTS should never go with driver changes or with driver trees, not only
because it hides ABI breaks but also for above reasons. The best if you
just drop or revert DTS commits, so they can go via platform maintainer.

Best regards,
