Merge tag 'devicetree-for-7.1' of git://git.kernel.org/pub/scm/linux/kernel/git/robh/linux
Pull devicetree updates from Rob Herring:
"DT core:
- Cleanup of the reserved memory code to keep CMA specifics in CMA
code
- Add and convert several users to new of_machine_get_match() helper
- Validate nul termination in string properties
- Update dtc to upstream v1.7.2-69-g53373d135579
- Limit matching reserved memory devices to /reserved-memory nodes
- Fix some UAF in unittests
- Remove Baikal SoC bus driver
- Fix false DT_SPLIT_BINDING_PATCH checkpatch warning
- Allow fw_devlink device-tree on x86
- Fix kerneldoc return description for of_property_count_elems_of_size()
DT bindings:
- Add fsl,imx25-aips, fsl,imx25-tcq, qcom,eliza-pdc,
qcom,eliza-spmi-pmic-arb, qcom,hawi-imem, qcom,milos-imem,
qcom,hawi-pdc, and lg,sw49410 bindings
- Convert arm,vexpress-scc to DT schema
- Deprecate Qualcomm generic CPU compatibles. Add Apple M3 CPU cores.
- Move some dual-link display panels to the dual-link schema
- Drop mux controller node name constraints
- Remove Baikal SoC bus bindings
- Fix a false warning in the thermal trip node binding"
