Merge tag 'devicetree-for-5.18' of git://git.kernel.org/pub/scm/linux/kernel/git/robh/linux

Pull devicetree updates from Rob Herring:

 - Add Krzysztof Kozlowski as co-maintainer for DT bindings providing
   much needed help.

 - DT schema validation now takes DTB files as input rather than
   intermediate YAML files. This decouples the validation from the
   source level syntax information. There's a bunch of schema fixes as a
   result of switching to DTB based validation which exposed some errors
   and incomplete schemas and examples.

 - Kbuild improvements to explicitly warn users running 'make
   dt_binding_check' on missing yamllint

 - Expand DT_SCHEMA_FILES kbuild variable to take just a partial
   filename or path instead of the full path to 1 file.

 - Convert various bindings to schema format: mscc,vsc7514-switch,
   multiple GNSS bindings, ahci-platform, i2c-at91, multiple UFS
   bindings, cortina,gemini-sata-bridge, cortina,gemini-ethernet, Atmel
   SHA, Atmel TDES, Atmel AES, armv7m-systick, Samsung Exynos display
   subsystem, nuvoton,npcm7xx-timer, samsung,s3c2410-i2c, zynqmp_dma,
   msm/mdp4, rda,8810pl-uart

 - New schemas for u-boot environment variable partition, TI clksel

 - New compatible strings for Renesas RZ/V2L SoC

 - Vendor prefixes for Xen, HPE, deprecated Synopsys, deprecated
   HiSilicon

 - Add/fix schemas for QEMU Arm 'virt' machine

 - Drop unused of_alias_get_alias_list() function

 - Add a script to check DT unittest EXPECT message output. Pass
   messages also now print by default at PR_INFO level to help test
   automation.
