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

-EEPROMs (SPI) compatible with Microchip Technology 93xx46 family.
-
-Required properties:
-- compatible : shall be one of:
-    "atmel,at93c46"
-    "atmel,at93c46d"
-    "atmel,at93c56"
-    "atmel,at93c66"
-    "eeprom-93xx46"
-    "microchip,93lc46b"
-- data-size : number of data bits per word (either 8 or 16)
-
-Optional properties:
-- read-only : parameter-less property which disables writes to the EEPROM
-- select-gpios : if present, specifies the GPIO that will be asserted prior to
-  each access to the EEPROM (e.g. for SPI bus multiplexing)
-
-Property rules described in Documentation/devicetree/bindings/spi/spi-bus.txt
-apply.  In particular, "reg" and "spi-max-frequency" properties must be given.
-
-Example:
-	eeprom@0 {
-		compatible = "eeprom-93xx46";
-		reg = <0>;
-		spi-max-frequency = <1000000>;
-		spi-cs-high;
-		data-size = <8>;
-		select-gpios = <&gpio4 4 GPIO_ACTIVE_HIGH>;
-	};
