Merge tag 'soc-fixes-6.9-1' of git://git.kernel.org/pub/scm/linux/kernel/git/soc/soc
Pull SoC fixes from Arnd Bergmann:
"The device tree changes this time are all for NXP i.MX platforms,
addressing issues with clocks and regulators on i.MX7 and i.MX8.
The old OMAP2 based Nokia N8x0 tablet get a couple of code fixes for
regressions that came in.
The ARM SCMI and FF-A firmware interfaces get a couple of minor bug
fixes.
A regression fix for RISC-V cache management addresses a problem with
probe order on Sifive cores"
