Merge tag 'devicetree-fixes-for-6.11-1' of git://git.kernel.org/pub/scm/linux/kernel/git/robh/linux

Pull more devicetree updates from Rob Herring:
 "Most of this is a treewide change to of_property_for_each_u32() which
  was small enough to do in one go before rc1 and avoids the need to
  create of_property_for_each_u32_some_new_name().

   - Treewide conversion of of_property_for_each_u32() to drop internal
     arguments making struct property opaque

   - Add binding for Amlogic A4 SoC watchdog

   - Fix constraints for AD7192 'single-channel' property"

* tag 'devicetree-fixes-for-6.11-1' of git://git.kernel.org/pub/scm/linux/kernel/git/robh/linux:
  dt-bindings: iio: adc: ad7192: Fix 'single-channel' constraints
  of: remove internal arguments from of_property_for_each_u32()
  dt-bindings: watchdog: add support for Amlogic A4 SoCs
