It doesn't matter, all the i2c busses are missing the pullups.
Will fix the board DTS file later on an will report
Thanks for investigation! Is that problem in both DTS and also legacy
I guess legacy board code does not set i2c pull-ups either, as we
have that problem since the beginning of time. Anyway, let me first
check if enabling pullups really solves the issue, I hope to test that
in a couple of hours when I am back home.
Or you can do it yourself, it is just a matter of replacing PIN_INPUT
with PIN_INPUT_PULLUP in
for all the 3 ic2 busses
