I am just a little worrying that the "host-notify" can now be present in both controller AND slave nodes and might be a bit hard to understand. At the same time I don't have a better proposal for naming the binding for the controller. Please do not consider serie v2 I just posted few days ago and I will post a serie v3 updating the binding information and using the host-notify binding in the i2c-stm32f7 driver. Alain
