Merge tag 'devicetree-for-6.7' of git://git.kernel.org/pub/scm/linux/kernel/git/robh/linux
Pull devicetree updates from Rob Herring:
- Add a kselftest to check for unprobed DT devices
- Fix address translation for some 3 address cells cases
- Refactor firmware node refcounting for AMBA bus
- Add bindings for qcom,sm4450-pdc, Qualcomm Kryo 465 CPU, and
Freescale QMC HDLC
- Add Marantec vendor prefix
- Convert qcom,pm8921-keypad, cnxt,cx92755-wdt, da9062-wdt, and
atmel,at91rm9200-wdt bindings to DT schema
- Several additionalProperties/unevaluatedProperties on child node
schemas fixes
- Drop reserved-memory bindings which now live in dtschema project
- Fix a reference to rockchip,inno-usb2phy.yaml
- Remove backlight nodes from display panel examples
- Expand example for using DT_SCHEMA_FILES
- Merge simple LVDS panel bindings to one binding doc
