You are welcome :)

I think it just needs to be tested/configured in DT if it does not work.
So this is a work package with real hardware in your hands...

BTW: the BME280 has two sensors in one and the BMP085 should be very similar.
AFAIR the BMC150 also has two chips inside (BMM150 and some BMA220). For the latter there is also a driver.

No. Would have needed 4 wires to go around the board - and we do not need very high speed (polling frequency i s usually <10Hz).

Yes, I have a contact to the designer of the BNO055 chip but would have to ask first if he can support someone else.
