From b56ba8aa6f3aeab23d3d4b1190ed1098463b2a9c Mon Sep 17 00:00:00 2001 From: Colin Tuckley Date: Wed, 24 Feb 2010 15:23:10 +0100 Subject: ARM: 5957/1: ARM: RealView SD/MMC Card detection and write-protect using GPIOLIB The switch to using GPIOLIB broke the sd/mmc card detection on the RealView development boards if GPIO_PL061 was not selected. This patch selects GPIO_PL061 if GPIOLIB is selected. The sense of the return value from mmc_status has also changed and is corrected.
