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

This is a child-node of "/reserved-memory", and -is named "ramoops" after the backend, rather than "pstore" which is the -subsystem. - -Parts of this storage may be set aside for other persistent log buffers, such -as kernel log messages, or for optional ECC error-correction data. The total -size of these optional buffers must fit in the reserved region. - -Any remaining space will be used for a circular buffer of oops and panic -records. These records have a configurable size, with a size of 0 indicating -that they should be disabled. - -At least one of "record-size", "console-size", "ftrace-size", or "pmsg-size" -must be set non-zero, but are otherwise optional as listed below. - - -Required properties: - -- compatible: must be "ramoops" - -- reg: region of memory that is preserved between reboots - - -Optional properties: - -- ecc-size: enables ECC support and specifies ECC buffer size in bytes - (defaults to 0: no ECC) - -- record-size: maximum size in bytes of each kmsg dump. - (defaults to 0: disabled) - -- console-size: size in bytes of log buffer reserved for kernel messages - (defaults to 0: disabled) - -- ftrace-size: size in bytes of log buffer reserved for function tracing and - profiling (defaults to 0: disabled) - -- pmsg-size: size in bytes of log buffer reserved for userspace messages - (defaults to 0: disabled) - -- mem-type: if present, sets the type of mapping is to be used to map the - reserved region. mem-type: 0 = write-combined (default), 1 = unbuffered, - 2 = cached. - -- unbuffered: deprecated, use mem_type instead.

If - both are specified -- "mem_type" overrides "unbuffered". - -- max-reason: if present, sets maximum type of kmsg dump reasons to store - (defaults to 2: log Oopses and Panics).
