From da764f97df0e5e05e5453279f934531c0cf52e11 Mon Sep 17 00:00:00 2001 From: Viresh Kumar Date: Fri, 28 Sep 2012 15:58:23 +0530 Subject: [PATCH] mmc: sdhci-spear: Add clk_{un}prepare() support clk_{un}prepare is mandatory for platforms using common clock framework. Since this driver is used by SPEAr platform, which supports common clock framework, add clk_{un}prepare() support for it.
