Merge tag 'devicetree-for-5.16' of git://git.kernel.org/pub/scm/linux/kernel/git/robh/linux

Pull devicetree updates from Rob Herring:

 - Convert /reserved-memory bindings to schemas

 - Convert a bunch of NFC bindings to schemas

 - Convert bindings to schema: Xilinx USB, Freescale DDR controller, Arm
   CCI-400, UBlox Neo-6M, 1-Wire GPIO, MSI controller, ASpeed LPC, OMAP
   and Inside-Secure HWRNG, register-bit-led, OV5640, Silead GSL1680,
   Elan ekth3000, Marvell bluetooth, TI wlcore, TI bluetooth, ESP
   ESP8089, tlm,trusted-foundations, Microchip cap11xx, Ralink SoCs and
   boards, and TI sysc

 - New binding schemas for: msi-ranges, Aspeed UART routing controller,
   palmbus, Xylon LogiCVC display controller, Mediatek's MT7621 SDRAM
   memory controller, and Apple M1 PCIe host

 - Run schema checks for %.dtb targets

 - Improve build time when using DT_SCHEMA_FILES

 - Improve error message when dtschema is not found

 - Various doc reference fixes in MAINTAINERS

 - Convert architectures to common CPU h/w ID parsing function
   of_get_cpu_hwid().

 - Allow for empty NUMA node IDs which may be hotplugged

 - Cleanup of __fdt_scan_reserved_mem()

 - Constify device_node parameters

 - Update dtc to upstream v1.6.1-19-g0a3a9d3449c8. Adds new checks
   'node_name_vs_property_name' and 'interrupt_map'.

 - Enable dtc 'unit_address_format' warning by default

 - Fix unittest EXPECT text for gpio hog errors
