Merge tag 'soc-late-6.9' of git://git.kernel.org/pub/scm/linux/kernel/git/soc/soc

Pull more ARM SoC updates from Arnd Bergmann:
 "These are changes that for some reason ended up not making it into the
  first four branches but that should still make it into 6.9:

   - A rework of the omap clock support that touches both drivers and
     device tree files

   - The reset controller branch changes that had a dependency on late
     bugfixes. Merging them here avoids a backmerge of 6.8-rc5 into the
     drivers branch

   - The RISC-V/starfive, RISC-V/microchip and ARM/Broadcom devicetree
     changes that got delayed and needed some extra time in linux-next
     for wider testing"
