Merge tag 'soc-arm-6.11' of git://git.kernel.org/pub/scm/linux/kernel/git/soc/soc
Pull arm SoC platform updates from Arnd Bergmann:
"The majority of the updates here are Dmitry Torokhov's cleanups for
platform code in the pxa and tegra platforms, changing custom
platform_data structures into DT-compatible software node
declarations.
The other updates are for the MAINTAINERS file, correcting some stale
or missing entries"
