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 9d02aa0382 dts: bindings: Make 'clocks' optional in pwm.yaml
Looks like no nodes with bindings that inherit pwm.yaml might be setting
'clocks'.

Now that the generation script doesn't look at the "generation" in the
YAML, we can remove it from the binding files.

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.

Kumar Gala 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.

This patch adds basic support for the PWM devices available on the Atmel
SAM family. Beside enabling the driver, everything is selected through

Diego Sueiro 9283ee7acc arch: i.MX add RDC peripheral permission setting for applications cores
This patch adds the RDC (Resource Domain Controller) peripheral
permissions settings for the i.MX applications cores (Cortex A9 on
i.MX6 and Cortex A7 on i.MX7).

This will enable both Linux (on application's core) and Zephyr (on M4
core) to share the peripherals and coexist.

The settings are defined at devicetree level and applied in the soc.c.

A complete solution should involve the SEMA4 to control the peripherals
access and prevent resource deadlocking and misusage.

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.
