I considered this but chose to keep pcie1 in order to preserve backward compatibility. I agree that it is debatable, because without the fix the old device tree can't work. However I find it better preserving the initial intent of an existing device tree. By talking about it, I think about an other option, keeping pcie1 name to setup the pins 39 and 40 how it was documented. And introducing pcie1_reset and pcie1_clkreq for new binding. however I don't know how it could be handle by the pinctrl framework. Gregory
