Merge tag 'devicetree-for-5.15' of git://git.kernel.org/pub/scm/linux/kernel/git/robh/linux

Pull devicetree updates from Rob Herring:

 - Refactor arch kdump DT related code to a common implementation

 - Add fw_devlink tracking for 'phy-handle', 'leds', 'backlight',
   'resets', and 'pwm' properties

 - Various clean-ups to DT FDT code

 - Fix a runtime error for !CONFIG_SYSFS

 - Convert Synopsys DW PCI and derivative binding docs to schemas. Add
   Toshiba Visconti PCIe binding.

 - Convert a bunch of memory controller bindings to schemas

 - Covert eeprom-93xx46, Samsung Exynos TRNG, Samsung Exynos IRQ
   combiner, arm-charlcd, img-ascii-lcd, UniPhier eFuse, Xilinx Zynq
   MPSoC FPGA, Xilinx Zynq MPSoC reset, Mediatek mmsys, Gemini boards,
   brcm,iproc-i2c, faraday,ftpci100, and ks8851 net to DT schema.

 - Extend nvmem bindings to handle bit offsets in unit-addresses

 - Add DT schemas for HiKey 970 PCIe PHY

 - Remove unused ZTE, energymicro,efm32-timer, and Exynos SATA bindings

 - Enable dtc pci_device_reg warning by default

 - Fixes for handling 'unevaluatedProperties' in preparation to enable
   pending support in the tooling for jsonschema 2020-12 draft
