From 0d9f768fce67a53b9c2296789129d4dfb3f4996b Mon Sep 17 00:00:00 2001 From: Eric Miao Date: Tue, 6 Jan 2009 18:06:25 +0800 Subject: [ARM] pxa: move pxa_gpio_mode() outside of generic gpio.c Looks like we have to live with pxa_gpio_mode() for a while, giving its presence is actually making gpio.c not generic enough, let's move it temporarily outside before it can be fully purged.
