interrupts.

Fix all line-length errors detected by yamllint:

yamllint -f parsable -c .yamllint $( find -regex '.*\.y[a]*ml' ) | \

Using a limit is set to 100 columns, not touching the commandlines in
GitHub workflows (at least for now).

83bea9a796 dts: bindings: clean up redundant required false attributes
DTS property attributes are (by default) not required.

Explicitly specifying `required: false` is redundant.
Perhaps a warning to that effect would be useful.

b7624bc5cf drivers: i2c: mcux: lpi2c: add bus recovery support
Add I2C bus recovery support to the NXP MCUX LPI2C driver. Since the LPI2C
peripheral block does not natively support I2C bus recovery, recovery is
performed using GPIO bitbanging.

Fixes: #42574

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.

94b509ba9f dts: bindings: nxp: lpi2c: add bus idle timeout property
Add property for specifying the bus idle timeout for the NXP
i.MX/Kinetis LPI2C I2C controller.

Enabling the bus idle timeout helps the controller to recover from
e.g. EMC causing false clock pulses/spikes on the SCL line.

Without a timeout the LPI2C controller will assume that another bus
master took over the I2C bus and thus refuses to issue a I2C START
condition.

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.

fc887a80ca dts: bindings: Rename i2c.yaml to i2c-controller.yaml
Renaming bindings to consistently be called foo-controller.yaml for
controllers and foo-device.yaml for devices (last one mostly makes sense
for devices on buses and the like).

I was thinking of having a plain foo.yaml be the controller as well, but

    !include interrupt.yaml

reads much worse than

    !include interrupt-controller.yaml

Another advantage of this approach is that no binding changes meaning
(which could be risky). It's just adding suffixes to filenames.

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.
