Also make it an int so 0 is disabling the pull-up (EVIENB set to 1) 1 is enabling the pull-up (EVIENB set to 0) and do nothing when the property is not present. -- Alexandre Belloni, Bootlin (formerly Free Electrons) Embedded Linux and Kernel engineering https://bootlin.com -- 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
