Merge tag 'devicetree-for-6.14' of git://git.kernel.org/pub/scm/linux/kernel/git/robh/linux
Pull devicetree updates from Rob Herring:
"DT Bindings:
- Add Bindings for QCom QCS615 UFS, QCom IPQ5424 DWC3 USB, NXP imx7d
MIPI DSI, QCom SM8750 PDC, QCom MSM8976 SRAM, QCom ipq6018 temp
sensor, QCom QCS8300 Power Domain Controller, QCom QCS615 Power
Domain Controller, QCom QCS615 APSS, QCom QCS615 qfprom, QCom
QCS8300 remoteproc, Mediatek MT6328 PMIC, Allwinner A100 OPP, and
NXP iMX35 GPT
- Convert Altera socfpga-system, raspberrypi,bcm2835-power to DT
schema
- Add Siflower vendor prefix
- Cleanup display, interrupt-controller, and UFS binding examples'
indentation
- Document preferred line wrapping (the same as the rest of the
kernel)
DT Core:
- Add warning when of_property_read_bool() is used on non-boolean
properties
- Restore keeping bootloader DTB when booting with ACPI. Turns out
some x86 platforms relied on that. Shrug.
- Fix of_find_node_opts_by_path() handling of alias+path+options
- Fix resource bounds checking for empty resources
- A bunch of small fixes/cleanups all over from Zijun Hu
- Cleanups in bin_attribute handling"
