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

Pull devicetree updates from Rob Herring:
 "DT Bindings:

   - Convert and add a bunch of IBM FSI related bindings

   - Add a new schema listing legacy compatibles which will (probably)
     never be documented. This will silence various checks warning about
     them.

   - Add bindings for Sierra Wireless mangOH Green SPI IoT interface,
     new Arm 2024 Cortex and Neoverse CPUs, QCom sc8180x PDC, QCom SDX75
     GPI DMA, imx8mp/imx8qxp fsl,irqsteer, and Renesas RZ/G2UL CRU and
     CSI-2 blocks

   - Convert Spreadtrum sprd-timer, FSL cpm_qe, FSL fsl,ls-scfg-msi, FSL
     q(b)man-*, FSL qoriq-mc, and img,pdc-wdt bindings to DT schema

   - Drop obsolete stericsson,abx500.txt

  DT core:

   - Update dtc to upstream version v1.7.0-93-g1df7b047fe43

   - Add support to run DT validation on DTs with applied overlays

   - Add helper for creating boolean properties in dynamic nodes and use
     that for dynamic PCI nodes

   - Clean-up early parsing of '#{address,size}-cells'"
