Hi, The way pins, groups and functions are tied is too constraining for some controllers. It concerns mainly the ones we don't care about groups and functions, each pin can be muxed to any functions. The goal of these two patches is too remove some of the constraints. I have added the prototype of a pin controller and device tree to show the way I want to use these changes. I couldn't test it on boards using generic pinconf so I am not sure that I don't break something...
