From dc6ab07d8f158b6c0a86fc412215692b28632c23 Mon Sep 17 00:00:00 2001 From: Linus Walleij Date: Tue, 10 Sep 2013 13:15:18 +0200 Subject: ptp: switch to use gpiolib This platform supports gpiolib, so remove the custom API use and replace with calls to gpiolib. Also request the GPIO before starting to use it.
