I know that, but I have no easy access to it when the system is up and
running, contrary to +5V.

OK, great.

This is only a product brief, I was referring to the complete datasheet
for the device. Not sure if it can be downloaded publicly, I think I
got that one from our technical contacts at Fintek.

There is definitely support missing for many parts, but the hard part
is to get the datasheets and then write and review the driver code.

For board configurations, you can definitely help. If you can
contribute configuration files for all boards you have, this would be
welcome.
