From: Florian Fainelli Date: Thu, 6 Dec 2012 22:41:09 +0000 (+0000) Subject: remove the now deprecated /proc/adm8668 interface X-Git-Url: http://git.lede-project.org./?a=commitdiff_plain;h=f1e4da0389f24943aac7309ead6f07b1c99ac9d9;p=openwrt%2Fstaging%2Fyousong.git remove the now deprecated /proc/adm8668 interface Proper gpiolib support is hooked instead.
