This patch adds a driver that exposes a read-only interface to allow these signals to be read from user space. In addition this patch series provides the required bindings for this to the peach-pi Chromebook. -- To unsubscribe from this list: send the line "unsubscribe linux-kernel" in the body of a message to majordomo@vger.kernel.org More majordomo info at http://vger.kernel.org/majordomo-info.html Please read the FAQ at http://www.tux.org/lkml/
