From ba2d1ccffa97b69e0aa9bfe11ba91c3391452dbc Mon Sep 17 00:00:00 2001 From: John Crispin Date: Fri, 1 Apr 2016 07:11:34 +0000 Subject: [PATCH] ar71xx: WNR2200: enable control of all LEDs and buttons This patch provides full GPIO support for WNR2200 (LEDs and buttons). It exposes all LEDs to operating system, including Ethernet ones.
