1904d24b7c dts: bindings: fix up 'label' property description
The value of a label property isn't really the name of an API. It's
the name of a device, as passed to device_get_binding().

Let's just say that directly so people know what this means in
practice instead of what's currently used as the description, which is
harder to understand and not really accurate.

Convert driver to use the new device tree macro's instead of
dts_fixup.h based macros. This moves us closer to removing both
dts_fixup.h and per instance Kconfig symbols.

bdf58d11f0 dts: atmel sam: Add pinctrl support for SAM UART and USART
Add pinctl support for the SAM UART and SAM USART devices.  We update
the UART and USART bindings to have pinctrl-0 bindings that are expected
to have 2 phandles to the RX & TX pinctrl nodes.

The pinctrl nodes will have an 'atmel,pins' property that describes the
GPIO port, pin and periphal configuration for that pin.

We add sam*-pinctrl.dtsi files with all the various pin ctrl
configuration operations supported by the given SoC family.  These
files are based on data extracted from the Atmel ASF HAL
(in include/sam<FAMILY>/pio/*.h).

8f0018663f drivers: pinmux: rv32m1: Convert driver to new DT_INST macros
Convert driver to use DT_INST macros and remove related board per
instance Kconfig symbol usage.

Updated the openisa,rv32m1_vega-pinmux binding to require the label
property and updated the rv32m1.dtsi to add label properties for the
pinmux nodes.

Also update gpio_basic_api test to use DT_NODELABEL.

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: |/'

567c348167 scripts: dts: Generalize '#cells' to allow multiple sources
Implement a nice generalization suggested by Bobby Noelte.

Instead of having a generic #cells key in bindings, have source-specific
*-cells keys. Some examples:

    interrupt-cells:
        - irq
        - priority
        - flags

    gpio-cells:
        - pin
        - flags

    pwm-cells:
        - channel
        - period

This makes bindings a bit easier to read, and allows a node to be a
controller for many different 'phandle-array' properties.

The prefix before *-cells is derived from the property name, meaning
there's no fixed set of *-cells keys. This is possible because of the
earlier 'phandle-array' generalization.

The older #cells key is supported for backwards compatibility, but
generates a deprecation warning.

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.

93d3a42776 scripts: extract_includes_dts: Remove usage of cell_string yaml attribute
'cell_string' yaml attribute has been introduced in order to
help enforcement of specific string during defines generation.
This adds complexity in understanding script behavior as a black
box and create additional dependency which is not strictly required.

For node specific generation functions (pinctrl and interrupts),
this could be replaced directly by an hardcoded version
(as everyone used the same 'cell_string' anyway).
For extract_cells functions, string could be replaced by extracted
property name. As a consequence, we're now able to generate defines
for properties refering to these controllers via phandle.
For instance, in following node
 	spbtle-rf@0 {
 		compatible = "st,spbtle-rf";
 		reg = <0>;
		reset-gpios = <&gpioa 8 0>;
 	};
We'll be able to generate:
 #define ST_STM32_SPI_...LE_RF_0_RESET_GPIOS_CONTROLLER	"GPIOA"
 #define ST_STM32_SPI_...PBTLE_RF_0_RESET_GPIOS_FLAGS_0		0
 #define ST_STM32_SPI_..._SPBTLE_RF_0_RESET_GPIOS_PIN_0		8

Only impact for this whole change is for NXP clocks which were the
only ones using 'cell_string' attribute with a value different than
the default one.

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.
