Merge tag 'devicetree-for-6.19' of git://git.kernel.org/pub/scm/linux/kernel/git/robh/linux

Pull devicetree updates from Rob Herring:
 "DT bindings:

   - Convert lattice,ice40-fpga-mgr, apm,xgene-storm-dma,
     brcm,sr-thermal, amazon,al-thermal, brcm,ocotp, mt8173-mdp, Actions
     Owl SPS, Marvell AP80x System Controller, Marvell CP110 System
     Controller, cznic,moxtet, and apm,xgene-slimpro-mbox to DT schema
     format

   - Add i.MX95 fsl,irqsteer, MT8365 Mali Bifrost GPU, Anvo ANV32C81W
     EEPROM, and Microchip pic64gx PLIC

   - Add missing LGE, AMD Seattle, and APM X-Gene SoC platform
     compatibles

   - Updates to brcm,bcm2836-l1-intc, brcm,bcm2835-hvs, and bcm2711-hdmi
     bindings to fix warnings on BCM2712 platforms

   - Drop obsolete db8500-thermal.txt

   - Treewide clean-up of extra blank lines and inconsistent quoting

   - Ensure all .dtbo targets are applied to a base .dtb

   - Speed up dt_binding_check by skipping running validation on empty
     examples

  DT core:

   - Add of_machine_device_match() and of_machine_get_match_data()
     helpers and convert users treewide

   - Fix bounds checking of address properties in FDT code. Rework the
     code to have a single implementation of the bounds checks.

   - Rework of_irq_init() to ignore any implicit interrupt-parent (i.e.
     in a parent node) on nodes without an interrupt. This matches the
     spec description and fixes some RISC-V platforms.

   - Avoid a spurious message on overlay removal

   - Skip DT kunit tests on RISCV+ACPI"
