Subsystem/interface for a 16x2 character LCD driver?

If you have any idea where/who I can ask, do not hesitate. Additionally,
if someone has thoughts on what the DT interface should look like for
such a device, I am interested.

You should probably take a look at the "panel" driver in staging. It's
a driver I wrote 10-15 years ago and that someone submitted. It supports
most 2-line text LCD panels with various wirings (serial/parallel), and
relies on parport to drive them. You can probably reuse some/most of it
for your driver. You may also possibly add a new backend to it to access
GPIOs. Userland drives it by writing into /dev/lcd. I don't know if that
can help.

Will take a look. Thanks.

Cheers,
