Hi @LinusJungemann , thanks for your contribution!
Could you please make sure that the linting is successful? That will ensure that the style of your changes is in line with the rest of the repository.

To setup pre-commit correctly, you can use the pre-commit configuration file that is provided in the repository. If there are issues to run pre-commit in the Docker container, a separate Python 3.10 environment can be used for that as well.

Hi @auphelia, sorry I was not able to fix the linting until now, because of other stuff I had to do.
It should be fixed now with the proper githook.

Thanks @LinusJungemann .
Overall the PR looks good, there is just a small change request in the driver_base and could you please clarify how you determined the settings for the U55C platform in platforms.py?
