From 067bf748bde70154a1fe1734b01f82b827c65b23 Mon Sep 17 00:00:00 2001 From: Viresh Kumar Date: Fri, 28 Sep 2012 15:58:22 +0530 Subject: mmc: sdhci-spear: add device tree bindings This adds simple DT bindings for SDHCI SPEAr controller. It uses cd-gpios from common mmc bindings. This also fixes spear300-evb.dts with correct name for card detect binding.
