Merge tag 'devicetree-for-6.6' of git://git.kernel.org/pub/scm/linux/kernel/git/robh/linux

Pull devicetree updates from Rob Herring:
 "DT core:

   - Add support for generating DT nodes for PCI devices. This is the
     groundwork for applying overlays to PCI devices containing
     non-discoverable downstream devices.

   - DT unittest additions to check reverted changesets, to test for
     refcount issues, and to test unresolved symbols. Also, various
     clean-ups of the unittest along the way.

   - Refactor node and property manipulation functions to better share
     code with old API and changeset API

   - Refactor changeset print functions to a common implementation

   - Move some platform_device specific functions into of_platform.c

  Bindings:

   - Treewide fixing of typos

   - Treewide clean-up of SPDX tags to use 'OR' consistently

   - Last chunk of dropping unnecessary quotes. With that, the check for
     unnecessary quotes is enabled in yamllint.

   - Convert ftgmac100, zynqmp-genpd, pps-gpio, syna,rmi4, and qcom,ssbi
     bindings to DT schema format

   - Add Allwinner V3s xHCI USB, Saef SF-TC154B display, QCom SM8450
     Inline Crypto Engine, QCom SM6115 UFS, QCom SDM670 PDC interrupt
     controller, Arm 2022 Cortex cores, and QCom IPQ9574 Crypto bindings

   - Fixes for Rockchip DWC PCI binding

   - Ensure all properties are evaluated on USB connector schema

   - Fix dt-check-compatible script to find of_device_id instances with
     compiler annotations"
