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"
