When do you not have an output? Seems kind of useless. I'm guessing this is an oversight in the binding and there should always be port 1 and a connector node, so document it that way. This also needs to state what port 0 and port 1 are (i.e. input or output and type of data).

Isn't this an analog input? bus-width doesn't make sense for that. Rob -- To unsubscribe from this list: send the line "unsubscribe devicetree" in the body of a message to majordomo-u79uwXL29TY76Z2rM5mHXA@public.gmane.org More majordomo info at http://vger.kernel.org/majordomo-info.html
