Ulf Magnusson 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:'.

Ulf Magnusson 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.

Ulf Magnusson 80a80d0405 dts: bindings: Rename adc.yaml to adc-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.

Ulf Magnusson 1480ad9ce7 dts: edtlib: Sanity-check the final merged binding only
Sanity-checking each !included file separately was inherited from the
old scripts. It makes it messy to check that combinations of fields make
sense, e.g. to check 'const:' or 'default:' against 'type:', since those
fields might come from different files (this is handy, since it makes
sense to just add/change a 'const:' value, for example).

Drop the requirement that each !included file is a complete binding in
itself, and treat them as binding fragments instead. Only check the
final merged binding.

This also means that !included files no longer need to have a
'description:' or 'title:' (those have always been unused for !included
files), so remove those, and add comments that explain what the
fragments are for instead. That should demystify bindings a bit.

Also fix the descriptions of i2c.yaml, i2s.yaml, spi.yaml, and
uart.yaml. They're for controllers, not devices. These are copy-paste
error from the corresponding device .yaml files.

Piggyback some indentation consistency nits in binding-template.yaml.

Ulf Magnusson 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.

Ulf Magnusson c023495df0 dts: bindings: Make 'clocks' optional in adc.yaml
These bindings !include adc.yaml, but their device tree nodes never set
'clocks':

    dts/bindings/iio/adc/atmel,sam-afec.yaml
    dts/bindings/iio/adc/atmel,sam0-adc.yaml
    dts/bindings/iio/adc/nordic,nrf-adc.yaml
    dts/bindings/iio/adc/nordic,nrf-saadc.yaml

The nodes for these bindings do set it (think it's consistent for
st,stm32-adc.yaml):

    dts/bindings/iio/adc/nxp,kinetis-adc12.yaml
    dts/bindings/iio/adc/st,stm32-adc.yaml

Make 'clocks' optional in adc.yaml. Maybe it should be changed to
required on some platforms (!including bindings can change 'optional' to
'required').

Ulf Magnusson 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.

Move common properties like 'compatible', 'reg', 'reg-names',
'interrupts', 'interrupt-names', and 'label' into one common base.yaml

'soc-nv-flash.yaml' to use base.yaml.

Erwan Gouriou 104553d93f yaml: fix properties syntax to 'mapping' instead of 'series'
According to yaml syntaxic rules, 'properties' described in dts
bindings yaml files could be seen as 'mapping'(key/value couple),
instead of 'series' (list of single elements).
yaml 'mappings' will then be converted by yaml python library as
python 'dict' which will ease treatment (instead of current list
as were before this commit).
Same treatment is applied to 'inherits'.

script extract_dts_inlcude is updated to take change of yaml_list
structre into account. This allows some code simplification. Largest
impact is yaml_collapse function which works now allow complete
overload method on all the attributes of a yaml nodes.
