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. * tag 'devicetree-for-5.18' of git://git.kernel.org/pub/scm/linux/kernel/git/robh/linux: (96 commits) dt-bindings: kbuild: Make DT_SCHEMA_LINT a recursive variable dt-bindings: nvmem: add U-Boot environment variables binding dt-bindings: ufs: qcom: Add SM6350 compatible string dt-bindings: dmaengine: sifive,fu540-c000: include generic schema dt-bindings: gpio: pca95xx: drop useless consumer example Revert "of: base: Introduce of_alias_get_alias_list() to check alias IDs" dt-bindings: virtio,mmio: Allow setting devices 'dma-coherent' dt-bindings: gnss: Add two more chips dt-bindings: gnss: Rewrite sirfstar binding in YAML dt-bindings: gnss: Modify u-blox to use common bindings dt-bindings: gnss: Rewrite common bindings in YAML dt-bindings: ata: ahci-platform: Add rk3568-dwc-ahci compatible dt-bindings: ata: ahci-platform: Add power-domains property dt-bindings: ata: ahci-platform: Convert DT bindings to yaml dt-bindings: kbuild: Use DTB files for validation dt-bindings: kbuild: Pass DT_SCHEMA_FILES to dt-validate dt-bindings: Add QEMU virt machine compatible dt-bindings: arm: Convert QEMU fw-cfg to DT schema dt-bindings: i2c: at91: Add SAMA7G5 compatible strings list dt-bindings: i2c: convert i2c-at91 to json-schema ...

-* QEMU Firmware Configuration bindings for ARM
-
-QEMU's arm-softmmu and aarch64-softmmu emulation / virtualization targets
-provide the following Firmware Configuration interface on the "virt" machine
-type:
-
-- A write-only, 16-bit wide selector (or control) register,
-- a read-write, 64-bit wide data register.
-
-QEMU exposes the control and data register to ARM guests as memory mapped
-registers; their location is communicated to the guest's UEFI firmware in the
-DTB that QEMU places at the bottom of the guest's DRAM.
-
-The authoritative guest-side hardware interface documentation to the fw_cfg
-device can be found in "docs/specs/fw_cfg.txt" in the QEMU source tree.
-
-
-Required properties:
-
-- compatible: "qemu,fw-cfg-mmio".
-
-- reg: the MMIO region used by the device.
- * Bytes 0x0 to 0x7 cover the data register.
- * Bytes 0x8 to 0x9 cover the selector register.
- * Further registers may be appended to the region in case of future interface
- revisions / feature bits.
-
-Example:
-
-/ {
- #size-cells = <0x2>;
- #address-cells = <0x2>;
-
- fw-cfg@9020000 {
- compatible = "qemu,fw-cfg-mmio";
