From: Kuninori Morimoto Date: Fri, 11 Nov 2011 02:44:24 +0000 (-0800) Subject: ARM: mach-shmobile: sh73a0: add MMC data pin pull-up X-Git-Url: https://git.stricted.de/?a=commitdiff_plain;h=052008edf31383f866b2ec1b12604fc411c2d986;p=GitHub%2Fexynos8895%2Fandroid_kernel_samsung_universal8895.git ARM: mach-shmobile: sh73a0: add MMC data pin pull-up This patch adds MMC data pin pull-up option for pfc-sh73a0.c, and select it on ag5evm board. The MMC read/write will be error without this patch.
