Hi, I tried to check the timing stuff but (as I'm not a real developper) I don't know how to test my timings easily. Until now, I did several tries with no luck...
In fact, for each try, I have to compile the module, load it, check what's going on and the reboot. I must reboot because the modesetting-101 branch does not support "rmmod". I would like to know if there is some sample code I can borrow to check the i2c (initiate queries, ...) in order to try to find the appropriate timing.
