15db98a400 dtlib: allow dangling aliases with DT(..., force=True)
As a first step towards being more forgiving on invalid inputs, allow
string-valued aliases properties that do not point to valid nodes when
the user requests permissiveness.

bd122e5ea2 edtlib: validate compatible properties
Error out on compatible properties with invalid values. The regular
expression used to validate them matches what's used in dt-schema.

b13b5b8b3a dtlib: fix include_path edge case
The documentation says DT.__init__ takes any iterable for the
include_path, but this leads to bad results when you pass it something
other than a 'real' sequence (list/tuple/etc), like a generator:

>>> dt = DT('/tmp/foo.dts', (x for x in ['a', 'b', 'c']))
>>> repr(dt)
"DT(filename='/tmp/foo.dts', include_path=<generator object ...>)"

Make a copy in list form just to avoid things like this.

Add a test for this and relax the regular expression in the existing
test case related to this.

74f95688d9 dtlib: add Type enum
Instead of hard-coding constants, use an IntEnum.

These is still a subclass of 'int', but is both easier to import and
easier to read during debugging.

For example, compare:

>>> Type.BYTES
<Type.BYTES: 1>

with:

>>> TYPE_BYTES
1

However, 'Type.BYTES == 1' is still True, and the enum values
otherwise behave like you would expect.

6e01c6abb6 scripts: edt: Add support for include property filtering
Add the ability to filter which properties get imported when we do an
include.  We add a new YAML form for this:

include:
  - name: other.yaml
    property-blocklist:
      - prop-to-block

or

include:
  - name: other.yaml
    property-allowlist:
      - prop-to-allow

These lists can intermix simple file names with maps, like:

include:
  - foo.yaml
  - name: bar.yaml
    property-allowlist:
      - prop-to-allow

And you can filter from child bindings like this:

include:
  - name: bar.yaml
    child-binding:
      property-allowlist:
        - child-prop-to-allow

5332847644 dts: separate DT libraries from gen_defines.py
We are now in the process of extracting edtlib and dtlib into a
standalone source code library that we intend to share with other
projects.

Links related to the work making this standalone:

    https://pypi.org/project/devicetree/
    https://python-devicetree.readthedocs.io/en/latest/
    https://github.com/zephyrproject-rtos/python-devicetree

This standalone repo includes the same features as what we have in
Zephyr, but in its own 'devicetree' python package with PyPI
integration, etc.

To avoid making this a hard fork, move the code that's being made
standalone around in Zephyr into a new scripts/dts/python-devicetree
subdirectory, and handle the package and sys.path changes in the
various places in the tree that use it.

From now on, it will be possible to update the standalone repository
by just recursively copying scripts/dts/python-devicetree's contents
into it and committing the results.

This is an interim step; do NOT 'pip install devicetree' yet.
The code in the zephyr repository is still the canonical location.

(In the long term, people will get the devicetree package from PyPI
just like they do the 'yaml' package today, but that won't happen for
the foreseeable future.)

This commit is purely intended to avoid a hard fork for the standalone
code, and no functional changes besides the package structure and
location of the code itself are expected.
