For Colibri Evaluation Board, those pins are routed to the generic 4-wire pins of the Colibri SO-DIMM. On the Colibri T30 module, those pins are connected to a STMPE811. I also added that to the device tree once, however it does not work properly atm, I need to debug this and will send a patch at a later time. -- Stefan -- To unsubscribe from this list: send the line "unsubscribe linux-tegra" in the body of a message to majordomo@xxxxxxxxxxxxxxx More majordomo info at http://vger.kernel.org/majordomo-info.html
