Merge tag 'soc-arm-6.6' of git://git.kernel.org/pub/scm/linux/kernel/git/soc/soc

Pull ARM SoC cleanups from Arnd Bergmann:
 "These are all minor cleanups for platform specific code in arch/arm/
  and some of the associated drivers. The majority of these are work
  done by Rob Herring to improve the way devicetreee header files are
  handled"

+==============================================
+SoC Platforms with DTS Compliance Requirements
+==============================================
+
+Overview
+--------
+
+SoC platforms or subarchitectures should follow all the rules from
+Documentation/process/maintainer-soc.rst.  This document referenced in
+MAINTAINERS impose additional requirements listed below.
+
+Strict DTS DT Schema and dtc Compliance
+---------------------------------------
+
+No changes to the SoC platform Devicetree sources (DTS files) should introduce
+new ``make dtbs_check W=1`` warnings.  Warnings in a new board DTS, which are
+results of issues in an included DTSI file, are considered existing, not new
+warnings.  The platform maintainers have automation in place which should point
+out any new warnings.
+
+If a commit introducing new warnings gets accepted somehow, the resulting
+issues shall be fixed in reasonable time (e.g. within one release) or the
+commit reverted.
