Hi Sebastian The current MPP code determines for itself what chip it is running on. It can then check if a pin configuration is valid for the current run time environment. Here you are suggesting we have to put into the DT what chip we expect to be on. What is the advantage of this, over getting the information from the device itself? If i wanted to mass convert all existing kirkwood DT boards over to use pinctrl, im stuck at the very first step. I've no idea what chip they use, it was not relevant before. Thanks Andrew
