Linus Torvalds f345fc7a07 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"

* tag 'devicetree-for-6.14' of git://git.kernel.org/pub/scm/linux/kernel/git/robh/linux: (50 commits)
  of: address: Fix empty resource handling in __of_address_resource_bounds()

  dt-bindings: ufs: qcom: Add UFS Host Controller for QCS615
  dt-bindings: usb: qcom,dwc3: Add IPQ5424 to USB DWC3 bindings
  dt-bindings: arm: coresight: Update the pattern of ete node name
  of: Warn when of_property_read_bool() is used on non-boolean properties
  device property: Split property reading bool and presence test ops
  of/fdt: Check fdt_get_mem_rsv() error in early_init_fdt_scan_reserved_mem()
  of: reserved-memory: Move an assignment to effective place in __reserved_mem_alloc_size()
  of: reserved-memory: Do not make kmemleak ignore freed address
  of: reserved-memory: Fix using wrong number of cells to get property 'alignment'
  of: Remove a duplicated code block
  of: property: Avoiding using uninitialized variable @imaplen in parse_interrupt_map()
  of: Correct child specifier used as input of the 2nd nexus node
  dt-bindings: interrupt-controller: ti,omap4-wugen-mpu: Add file extension
