b2a1eeb6ac soc: arc: define ICI in DT
ICI (Inter-Core Interrupt Unit) interrupts and priorities were hardcoded
in C files. This patch moves this information to Devicetree and updates
code to make use of it.

754c022fa2 soc: arc: snps_arc_iot: define sysconf in DT
sysconf base address was hardcoded in <soc.h>. Create a new compatible
and define it in Devicetree, where hardware needs to be described.

All in tree device drivers use some form of DEVICE_DT_GET

b804956a7d dts: misc: npcx: add new DT node for booter variant
The booter (bootloader) behavior may be different in different NPCX
chip series. One example is that the booter sets host interface type in
NPCX7 series but leave the firmware to set it in NPCX9 series.
This commit adds a new DT node to record variants in its properties.
NPCX drivers can understand if they need to configure the related
setting by checking the node's properties.

ce36a05953 misc: npcx: Add soc id node
Nuvoton provides different series MCU. The NPCX series has a specific
id, which can identify the real chip part number. This CL adds soc id
for the NPCX series.

2934ee2cda dts: bindings: Remove 'title:' and put all info. into 'description:'
Add any useful information from 'title:' to the 'description:' strings
(e.g. explanations of acronyms), and remove 'title:' as well as any
copy-pasted "this binding gives a ..." boilerplate.

Also clean some description strings up a bit.

Some other things could probably be cleaned up (replacing 'GPIO node'
with 'GPIO controller' on controllers for consistency, for example), but
I kept things close to the original to avoid accidentally messing up.

b9240a3cbc dts: bindings: Preserve newlines in descriptions
With https://github.com/zephyrproject-rtos/zephyr/pull/20185, multi-line
descriptions will be formatted nicely, but using '>' breaks it, because
it removes internal newlines (including between paragraphs).

See https://yaml-multiline.info/.

Replace 'description: >' with 'description: |' to encourage '|'. That'll
prevent '>' from getting copied around and messing up long descriptions.

This will lead to some extra newlines in the output, but it's fine.
Line-wrapping messes up any manual formatting.

The replacement was done with

    $ git ls-files 'dts/bindings/*.yaml' | \
          xargs sed -i 's/description:\s*>/description: |/'

a0fceff1a2 scripts: dts: Simplify and improve 'compatible' matching
Instead of

    properties:
        compatible:
            constraint: "foo"

, just have

    compatible: "foo"

at the top level of the binding.

For backwards compatibility, the old 'properties: compatible: ...' form
is still accepted for now, and is treated the same as a single-element
'compatible:'.

The old syntax was inspired by dt-schema (though it isn't
dt-schema-compatible), which is in turn a thin wrapper around
json-schema (the idea is to transform .dts files into YAML and then
verify them).

Maybe the idea was to gradually switch the syntax over to dt-schema and
then be able to use unmodified dt-schema bindings, but dt-schema is
really a different kind of tool (a completely standalone linter), and
works very differently from our stuff (see schemas/dt-core.yaml in the
dt-schema repo to get an idea of just how differently).

Better to keep it simple.

This commit also piggybacks some clarifications to the binding template
re. '#cells:'.

fcd665a26c dts: bindings: Have 'required: true/false' instead of 'category: ...'
The 'category: required/optional' setting for properties is just a
yes/no thing. Using a boolean makes it clearer, so have
'required: true/false' instead.

Print a clear error when 'category:' is used:

    edtlib.EDTError: please put 'required: true' instead of 'category:
    required' in 'properties: foo: ...' in
    test-bindings/sub-node-parent.yaml - 'category' has been removed

The old scripts in scripts/dts/ ignore this setting, and only print a
warning if 'category: required' in an inherited binding is changed to
'category: optional'. Remove that code, since the new scripts already
have the same check.

The replacement was done with

    git ls-files 'dts/bindings/*.yaml' | xargs sed -i \
        -e 's/category:\s*required/required: true/' \
        -e 's/category:\s*optional/required: false/'

dts/binding-template.yaml is updated as well.

0ec0c84808 dts: bindings: Remove unused 'version' field
No binding has anything but 'version: 0.1', and the code in scripts/dts/
never does anything with it except print a warning if it isn't there.
It's undocumented what it means.

I suspect it's overkill if it's meant to be the binding format version.
If we'd need to tell different versions from each other, we could change
some other minor thing in the format, and it probably won't be needed.

Remove the 'version' fields from the bindings and the warning from the
scripts/dts/ scripts.

The new device tree script will give an error when unknown fields appear
in bindings.

The deletion was done with

    git ls-files 'dts/bindings/*.yaml' | xargs sed -i '/^\s*version: /d'

Some blank lines at the beginning of bindings were removed as well.

eba81c6e54 yaml: Remove redundant document separators
YAML document separators are needed e.g. when doing

  $ cat doc1.yaml doc2.yaml | <parser>

For the bindings, we never parse concatenated documents. Assume we don't
for any other .yaml files either.

Having document separators in e.g. base.yaml makes !include a bit
confusing, since the !included files are merged and not separate
documents (the merging is done in Python code though, so it makes no
difference for behavior).

The replacement was done with

    $ git ls-files '*.yaml' | \
        xargs sed -i -e '${/\s*\.\.\.\s*/d;}' -e 's/^\s*---\s*$//'

First pattern removes ... at the end of files, second pattern clears a
line with a lone --- on it.

Some redundant blank lines at the end of files were cleared with

    $ git ls-files '*.yaml' | xargs sed -i '${/^\s*$/d}'

This is more about making sure people can understand why every part of a
binding is there than about removing some text.

48100df875 dts/bindings: Move common properties into a base.yaml
Move common properties like 'compatible', 'reg', 'reg-names',
'interrupts', 'interrupt-names', and 'label' into one common base.yaml
that all the other yaml's can inherit from.  This removes both
duplication and inconsistent definition.

The device specific yamls just need to say if a property is 'required'
or not.

NOTE: due to some generation conflicts we did not covert
'soc-nv-flash.yaml' to use base.yaml.
