From aee14423e79eddf3c4fa97d7015164d150b75e45 Mon Sep 17 00:00:00 2001 From: Guennadi Liakhovetski Date: Wed, 16 Jan 2013 08:54:18 +0100 Subject: [PATCH] ARM: shmobile: use GPIO SD-card detection on armadillo800eva Switch SDHI0 and SDHI1 SD-card interfaces on armadillo800eva to using GPIO card detection, which provides maximum power saving and automatically selects IRQ or polling mode, depending on the CD GPIO capability.
