Ok, thank you for pointing this out.
After some checks, this property doesn't match with what is done in this 
driver.

In the v2 series I am sending, I removed the I2C timing tuning as it 
works on all
the boards I have tested with.
I will only keep the anti-glitch filtering, using private properties as 
I didn't find any generic
ones that could fit.
