How does this driver even works ? I don't see any call to i2c_acquire/i2c_release.
Any clue captain ?

mhm only adapted the existing calls, it works on master with the old API even without the acquire. And if only one I2c device is present it should be fine without acquire and release. However, you're right it will get tricky if multiple i2c devs are present. Should I fix this?

I would love to test this device on master. I don't think this driver works for all MCUs (like SAM0 based). Shame I don't own this one...

Should I fix this?

Hum, I think it's safe to fix it. So yes please go ahead :)

@dylad added acquire and release calls. Could be improved but would need more restructuring, but wanted to keep it simple (for now) to get the I2C rework done.

Untested ACK.
It would be great to have someone test it or maybe @smlng you can share some outputs if you find some times
