Merge tag 'devicetree-for-5.17' of git://git.kernel.org/pub/scm/linux/kernel/git/robh/linux
Pull devicetree updates from Rob Herring:
"Bindings:
- DT schema conversions for Samsung clocks, RNG bindings, Qcom
Command DB and rmtfs, gpio-restart, i2c-mux-gpio, i2c-mux-pinctl,
Tegra I2C and BPMP, pwm-vibrator, Arm DSU, and Cadence macb
- DT schema conversions for Broadcom platforms: interrupt
controllers, STB GPIO, STB waketimer, STB reset, iProc MDIO mux,
iProc PCIe, Cygnus PCIe PHY, PWM, USB BDC, BCM6328 LEDs, TMON,
SYSTEMPORT, AMAC, Northstar 2 PCIe PHY, GENET, moca PHY, GISB
arbiter, and SATA
- Add binding schemas for Tegra210 EMC table, TI DC-DC converters,
- Clean-ups of MDIO bus schemas to fix 'unevaluatedProperties' issues
- More fixes due to 'unevaluatedProperties' enabling
- Data type fixes and clean-ups of binding examples found in
preparation to move to validating DTB files directly (instead of
intermediate YAML representation.
- Vendor prefixes for T-Head Semiconductor, OnePlus, and Sunplus
- Add various new compatible strings
DT core:
- Silence a warning for overlapping reserved memory regions
- Reimplement unittest overlay tracking
- Fix stack frame size warning in unittest
- Clean-ups of early FDT scanning functions
- Fix handling of "linux,usable-memory-range" on EFI booted systems
- Add support for 'fail' status on CPU nodes
- Improve error message in of_phandle_iterator_next()
- kbuild: Disable duplicate unit-address warnings for disabled nodes"
