Author: blogic Date: 2015-07-08 16:25:52 +0200 (Wed, 08 Jul 2015) New Revision: 46271
Added: trunk/package/base-files/files/etc/init.d/gpio_switch trunk/target/linux/ar71xx/base-files/etc/uci-defaults/01_gpio-switches Modified: trunk/package/base-files/files/lib/functions/uci-defaults.sh Log: base-files: implemented basic GPIO control Internal GPIO pins are used for PoE passthrough setups in multi-port routers. This patch implemnets control over this hardware feature for Ubiquiti Nanostations and TP-Link CPE510.
