Merge tag 'arm-fixes-6.11-1' of git://git.kernel.org/pub/scm/linux/kernel/git/soc/soc
Pull ARM SoC fixes from Arnd Bergmann:
"There are three sets of patches for the soc tree:
- Marek Behún addresses multiple build time regressions caused by
changes to the cznic turris-omnia support
- Dmitry Torokhov fixes a regression in the legacy "gumstix" board
code he cleaned up earlier
- The TI K3 maintainers found multiple bugs in the in gpio, audio and
pcie devicetree nodes"
