Isn't Maxime the author of this driver?
Yes i upstream with his agreement.
I only made small modifications (use of devm_reset_controller_register(),
make reset_control_ops const...) that's why the author in the git history has
been changed... I will use g |it commit --amend --author="Maxime.." for the v2.

The STM32 MCUs family IPs can be reset by accessing some registers
from the RCC block.

The list of available reset lines is documented in the DT bindings.

Are the registers not readable, or did you choose not to
implement .status on purpose?
We choose to not implement.

Thanks!
