The DU board code I've submitted for the Marzen board doesn't use the pinctrl 
API yet, as I wanted the DU DRM driver to be usable without waiting for the 
next pinctrl series to be ready. I will fix this later, either in the DU DRM 
driver patch series or in the pinctrl patch series, depending on which one is 
ready first.

In the meantime, please keep the branches separate.
