Merge tag 'devicetree-for-6.9' of git://git.kernel.org/pub/scm/linux/kernel/git/robh...

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'"
