Merge tag 'devicetree-for-5.10' of git://git.kernel.org/pub/scm/linux/kernel/git/robh/linux
Pull devicetree updates from Rob Herring:
- Update dtc to upstream version v1.6.0-31-gcbca977ea121
- dtx_diff help text reformatting
- Speed-up validation time for binding and dtb checks using json for
intermediate files
- Add support for running yamllint on DT schema files
- Remove old booting-without-of.rst
- Extend the example schema to address common issues
- Cleanup handling of additionalProperties/unevaluatedProperties
- Ensure all DSI controller schemas reference dsi-controller.yaml
- Vendor prefixes for Zealz, Wandbord/Technexion, Embest RIoT, Rex,
DFI, and Cisco Meraki
- Convert at25, SPMI bus, TI hwlock, HiSilicon Hi3660 USB3 PHY, Arm
SP805 watchdog, Arm SP804, and Samsung 11-pin USB connector to DT
schema
- Convert HiSilicon SoC and syscon bindings to DT schema
- Convert SiFive Risc-V L2 cache, PLIC, PRCI, and PWM to DT schema
- Convert i.MX bindings for w1, crypto, rng, SIM, PM, DDR, SATA, vf610
GPIO, and UART to DT schema
- Add i.MX 8M compatible strings
- Add LM81 and DS1780 as trivial devices
- Various missing properties added to fix dtb validation warnings
