Improve Dummy Implementation and not implemented functions in drivers. #677

fjtrujy · 2024-11-13T23:26:44Z

Description

This PR is for improving drive implementation, especially trying to identify those specific drivers that require a concrete value to be returned.

So far I have created another macro DUMMY_IMPLEMENTATION which just do:

int dummy_implementation_int(void) { return 0; }

This PR needs to be reviewed carefully as it has several changes, let me enumerate them:

init and deinit functions now always used either a custom function or a DUMMY_IMPLEMENTATION
All the functions that were return 0; were replaced to NOT_SUPPORTED (the ones that required s64 as return are using NOT_SUPPORTED_S64).
In the driver definition every single function has now a comment, which helps us to read the driver better.
Several functions were removed and replaced with DUMMY_IMPLEMENTATION or NOT_SUPPORTED.
In general I think it is a super good approach to return NOT_IMPLEMENTED for all these functions that aren't doing anything.

This PR as it is right now will raise most probably several issues, so the main scope of this PR is to identify together in each driver what are the specific functions that require concrete DUMMY_IMPLEMENTATION rather than NOT_SUPPORTED.

Please help me to identify them and then put a clear comment with the reason.

To test with OPL could be a good test, however, we need to keep in mind that, if it is not working maybe it is because OPL code itself needs to be updated.

Here you have all the drivers, the functions, and the previous and new value.
So far we have the next different kind of drivers:
