From a05dcdb98011a53d150d699ef8243754e2c9a61c Mon Sep 17 00:00:00 2001 From: Paul Walmsley Date: Fri, 25 Feb 2011 18:22:08 -0700 Subject: [PATCH] MMC: omap_hsmmc: enable interface clock before calling mmc_host_enable() The code path entered via mmc_host_enable() can include register accesses to the HSMMC IP block. For this to work, both the device interface clock and functional clock need to be enabled before mmc_host_enable() is called. However, omap_hsmmc_probe() calls mmc_host_enable() before enabling the device interface clock. Fix by calling mmc_host_enable() after the device interface clock is enabled.
