Merge tag 'devicetree-for-6.13' of git://git.kernel.org/pub/scm/linux/kernel/git/robh/linux

Pull devicetree updates from Rob Herring:
 "Bindings:

   - Enable dtc "interrupt_provider" warnings for binding examples. Fix
     the warnings in fsl,mu-msi and ti,sci-inta due to this.

   - Convert zii,rave-sp-wdt, zii,rave-sp-pwrbutton, and
     altr,fpga-passive-serial to DT schema format

   - Add some documentation on the different forms of YAML text blocks
     which are a constant source of review comments

   - Fix some schema errors in constraints for arrays

   - Add compatibles for qcom,sar2130p-pdc and onnn,adt7462

  DT core:

   - Allow overlay kunit tests to run CONFIG_OF_OVERLAY=n

   - Add some warnings on deprecated address handling

   - Rework early_init_dt_scan() so the arch can pass in the phys
     address of the DTB as __pa() is not always valid to use. This fixes
     a warning for arm64 with kexec.

   - Add and use some new DT graph iterators for iterating over ports
     and endpoints

   - Rework reserved-memory handling to be sized dynamically for fixed
     regions

   - Optimize of_modalias() to avoid a strlen() call

   - Constify struct device_node and property pointers where ever
     possible"
