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'" * tag 'devicetree-for-6.9' of git://git.kernel.org/pub/scm/linux/kernel/git/robh/linux: (56 commits) dt-bindings: soc: imx: fsl,imx-anatop: add imx6q regulators of: unittest: Use for_each_child_of_node_scoped() of: Introduce for_each_*_child_of_node_scoped() to automate of_node_put() handling of: Add cleanup.h based auto release via __free(device_node) markings of: Move all FDT reserved-memory handling into of_reserved_mem.c of: Add KUnit test to confirm DTB is loaded of: unittest: treat missing of_root as error instead of fixing up x86/of: Unconditionally call unflatten_and_copy_device_tree() um: Unconditionally call unflatten_device_tree() of: Create of_root if no dtb provided by firmware of: Always unflatten in unflatten_and_copy_device_tree() dt-bindings: timer: mediatek: Convert to json-schema dt-bindings: interrupt-controller: fsl,intmux: Include power-domains support soc: fsl: qbman: Remove RESERVEDMEM_OF_DECLARE usage dt-bindings: fsl-imx-sdma: fix HDMI audio index dt-bindings: soc: imx: fsl,imx-iomuxc-gpr: add imx6 dt-bindings: soc: imx: fsl,imx-anatop: add binding dt-bindings: input: touchscreen: fsl,imx6ul-tsc convert to YAML dt-bindings: pinctrl: fsl,imx6ul-pinctrl: convert to YAML of: make for_each_property_of_node() available to to !OF ...

-* Freescale i.MX6UL Touch Controller
-
-Required properties:
-- compatible: must be "fsl,imx6ul-tsc".
-- reg: this touch controller address and the ADC2 address.
-- interrupts: the interrupt of this touch controller and ADC2.
-- clocks: the root clock of touch controller and ADC2.
-- clock-names; must be "tsc" and "adc".
-- xnur-gpio: the X- gpio this controller connect to.
- This xnur-gpio returns to low once the finger leave the touch screen (The
- last touch event the touch controller capture).
-
-Optional properties:
-- measure-delay-time: the value of measure delay time.
- Before X-axis or Y-axis measurement, the screen need some time before
- even potential distribution ready.
- This value depends on the touch screen.
-- pre-charge-time: the touch screen need some time to precharge.
- This value depends on the touch screen.
-- touchscreen-average-samples: Number of data samples which are averaged for
- each read. Valid values are 1, 4, 8, 16 and 32.
-
-Example:
- tsc: tsc@2040000 {
- compatible = "fsl,imx6ul-tsc";
