Hi AngeloGioacchino,

Thank you for your review.
Indeed, you're right – we don't have any hardware that functions
solely as a reset controller. Our hardware only provides partial
reset capabilities, which necessitates a partial reset driver 
(responsible for managing just a few set/clear bits).

We are currently planning to remove the ti,syscon-reset implementation
and utilize a MediaTek-specific syscon-reset instead. However, 
if you object, I will halt this plan, and we can adopt
Philipp's proposed solution for handling the reset.

Thanks
Peter
