Merge tag 'devicetree-for-6.9' of git://git.kernel.org/pub/scm/linux/kernel/git/robh/linux
Pull devicetree updates from Rob Herring:
"DT core:
- Add cleanup.h based auto release of struct device_node pointers via
__free marking and new for_each_child_of_node_scoped() iterator to
use it.
- Always create a base skeleton DT when CONFIG_OF is enabled. This
supports several usecases of adding DT data on non-DT booted
systems.
- Move around some /reserved-memory code in preparation for further
improvements
- Add a stub for_each_property_of_node() for !OF
- Adjust the printk levels on some messages
- Fix __be32 sparse warning
- Drop RESERVEDMEM_OF_DECLARE usage from Freescale qbman driver
(currently orphaned)
- Add Saravana Kannan and drop Frank Rowand as DT maintainers
DT bindings:
- Convert Mediatek timer, Mediatek sysirq, fsl,imx6ul-tsc,
fsl,imx6ul-pinctrl, Atmel AIC, Atmel HLCDC, FPGA region, and
xlnx,sd-fec to DT schemas
- Add existing, but undocumented fsl,imx-anatop binding
- Add bunch of undocumented vendor prefixes used in compatible
strings
- Drop obsolete brcm,bcm2835-pm-wdt binding
- Drop obsolete i2c.txt which as been replaced with schema in
dtschema
- Add DPS310 device and sort trivial-devices.yaml
- Enable undocumented compatible checks on DT binding examples
- More QCom maintainer fixes/updates
- Updates to writing-schema.rst and DT submitting-patches.rst to
cover some frequent review comments
- Clean-up SPDX tags to use 'OR' rather than 'or'"
