98673d0aad scripts: ... :edtlib.py: update edtlib.py to generate some warning messages
During the actual development process, it was discovered that the
controller/device' would describe the bus type in the binding. However,
when the two sides did not match, the generated process would not be
affected and there were no any prompts. This made it very difficult for
developers to identify the problem.

I've updated the implementation to:
1. Add a `warn_bus_mismatch` kwarg to `edtlib.EDT()` constructor
   (default: False)
2. Add a `--warn-bus-mismatch` flag to gen_edt.py
3. Only show the warning when explicitly opted in
4. Add some checks in the edtlib. When the bus type of the node
   does not match the binding requirements, provide some auxiliary
   judgment information:
     a. bus position of the node
     b. available binding types
     c. expected binding type.

0907a05baf scripts: dts: fix CMake DT API helper for compatible properties
Our build system DT API has a dt_comp_path() function used to look up
paths of nodes with a given compatible. This relies on the generated
edt.pickle.cmake file in the build directory to look inside the
concrete devicetree for the current application build.

The script gen_dts_cmake.py is responsible for generating
edt.pickle.cmake. It currently generates the data needed by
dt_comp_path() by looking inside each edtlib.Node object's "props"
attribute. This attribute in turn is fed by the "properties:" key in
the node's YAML binding. This leads to an edge case which is breaking
the dt_comp_path() API.

In most cases, we don't notice this edge case because base.yaml, which
is included by nearly all bindings, has a definition for "compatible"
in its "properties:" map. However, bindings are not required to
include base.yaml, and bindings do not have to explicitliy define a
"compatible" entry in their "properties:". An example of a binding
that does neither is fixed-partitions.yaml: it only has #address-cells
and #size-cells in its "properties:".

Nonetheless, "compatible:" is always a valid property name because
it's defined in the DT spec, and we should make the CMake API robustly
detect all nodes with a given compatible, regardless of whether that
node's binding explicitly defines it or not.

To make this happen, rely on the edtlib.Node.compats attribute instead
of edtlib.Node.props. The compats attribute is always defined even if
the node's YAML binding doesn't have an explicit entry for
"compatible".

871afee41c edtlib: fix _raw_unit_addr() function
The '_raw_unit_addr()' function was incorrectly written a long time ago.
It tries to look up and use the '#address-cells' of the node containing
the 'interrupts' property itself, instead of using the '#address-cells' of
the interrupt controller's node (or its parent).

As a result, the mapping is successful only if the '#address-cells' value
is the same in both the node and the interrupt controller, all other cases
lead to random errors being generated by the 'gen_defines.py' script.

Also, the function was trying to use the '#address-cells' value as a
little-endian one, which led to unpredictable results as well.
This problem has been fixed too.

Fixes #77890, and probably #78020

1b1bfc9cc8 edtlib: Improve _interrupt_parent() function
According to the following comment on github
https://github.com/zephyrproject-rtos/zephyr/pull/77900/files#r1750393745
edtlib implementation is partially correct and it is missing two things:

1. If an ancestor has an interrupt-controller or interrupt-map property,
   the walk must terminate.
2. If an interrupt-parent property is found, the linked node must be a
   valid interrupt controller or nexus.

This commit add these checks.

0a4e2e383f scripts: dts: dtlib: improve formatting of long arrays
Split long arrays into multiple lines to improve readability of the
output DTS file. A new line is started when the array data exceeds
80 characters.

Add a few test entries to verify the new behavior.

Note: the F821 linter suppression prevents flagging 'array_start' and
'array_newline' as undefined variables. This is because these variables
are initialized when an opening brace is output, which is necessarily
before any element in a byte or prop array. A sequence of markers not
following this pattern would indicate a bug in the DTS parsing code.

c1603b3163 gen_edt: use workspace dir as base for relative paths in comments
This commit allows comments to reference files with paths that are relative
to the Zephyr workspace root. This is done by adding a new argument
'--workspace-dir' to the 'gen_edt.py' script, which is passed to the
'EDT' and 'DT' classes and used instead of the current working directory.

The workspace directory is set to WEST_TOPDIR if West is in use,
otherwise it is set to the parent directory of ZEPHYR_BASE so that
Zephyr files have a 'zephyr/' prefix.

15488be6af scripts: dts: Refactor gen_driver_kconfig_dts
The motivation for this patch was to improve the script's performance,
but some stylistic changes and cleanups are included as well.

The main optimization concerns the use of PyYAML, as it offers multiple
functions for interpreting YAML. The commonly used `load`/`safe_load`
converts a YAML stream to a dictionary. There are also `scan`, `parse`,
and `compose`, which return intermediate representations, the last one
being a graph. [1]

Since `gen_driver_kconfig_dts` scans DT bindings for compatible strings,
it only needs to look through top level keys in YAML. The intermediate
PyYAML graph is sufficient for this, and using it reduces the script's
execution time by about 30%, without making the code too complicated.
