From 909ceef6827c579e767f093b422313945f9cba53 Mon Sep 17 00:00:00 2001 From: Thomas Abraham Date: Wed, 28 Sep 2011 10:59:34 +0900 Subject: ARM: SAMSUNG: remove sdhci default configuration setup platform helper The sdhci platform helper function that sets up the default controller configuration is removed for all Samsung platforms since such default controller configuration can be handled by the driver.
