For example, Rudolf Marek just posted a patch adding support for the
It should be fairly easy to review. Of course I'll end up doing it if
nobody picks it shortly, but it's probably a good one to get started.

Are you sure it is an ITE chip? ID 0xea doesn't sound like an ITE chip
at all, more like National Semiconductor. The earlier versions of
sensors-detect might have been confusing in that respect, please check
again with a recent version.
The adm1021 driver is still using macro-generated functions instead of
dynamic callbacks, and doesn't implement individual alarm files. So
these are two things you could work on if you feel like it.

Same thing for the w83781d driver, dynamic callbacks and individual
alarm files are missing.

Basically my problem is that I can't get the driver to bind to my
device. I am able to "talk" to the device using minicom so I know the
serial port and the device work OK. But I don't know how to write a
kernel driver which will bind to the serial port and let me read and
write "raw" characters from and to it. I tried copying random examples
from other serial drivers but my .connect() method never gets called.
LDD3 unfortunately doesn't cover legacy serial drivers.
