With increasing amounts of the platform moving into the CPU and PCH this is of course also becoming more and more rare. Even on actual PCs we have seen some truly "special" facepalms. There was the Olivetti machine which used the GPIO for "fast A20" to control the screen backlight, for example. That one was fun to deal with. -hpa -- To unsubscribe from this list: send the line "unsubscribe devicetree" in the body of a message to majordomo@xxxxxxxxxxxxxxx More majordomo info at http://vger.kernel.org/majordomo-info.html
