Yong Cong Sin 450a66fa36 gen_defines: output the interrupt level of a node Currently it is tedious to know the level of an interrupt for a node in C. One would have to go through a very complex and error prone macros to check if there's a parent interrupt controller & if the controller has an interrupt number and thus not a pseudo interrupt controller like the one found in `rv32m1`. The level of a node is required to encode the Zephyr's multi-level interrupt number Since it is easier to do it in the `gen_defines` script, let's do the heavy lifting there so that we can introduce new DT macros to get the interrupt level very easily later.

README.txt

This directory used to contain the edtlib.py and dtlib.py libraries
and tests, alongside the gen_defines.py script that uses them for
converting DTS to the C macros used by Zephyr.

The libraries and tests have now been moved to the 'python-devicetree'
subdirectory.

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

The 'python-devicetree' subdirectory you find here next to this
README.txt matches the standalone python-devicetree repository linked
above.

For now, the 'main' copy will continue to be hosted here in the zephyr
repository. We will mirror changes into the standalone repository as
needed; you can just ignore it for now.

Code in the zephyr repository which needs these libraries will import
devicetree.edtlib from now on, but the code will continue to be found
by manipulating sys.path for now.

Eventually, as APIs stabilize, the python-devicetree code in this
repository will disappear, and a standalone repository will be the
'main' one.
