From 23920c0552a462a095b9afa044ebedf8f9201c53 Mon Sep 17 00:00:00 2001 From: Dinh Nguyen Date: Thu, 16 Oct 2014 14:54:51 -0500 Subject: ARM: dts: socfpga: Fix SD card detect Without this patch, the booting the SOCFPGA platform would hang at the SDMMC driver loading. The issue, debugged by Doug Anderson, turned out to be that the GPIO bank used by the SD card-detect was not set to status="okay". Also update the cd-gpios to point to portb of the &gpio1 GPIO IP.
