From 514d9eda92654430369060b91f7472bb198e7904 Mon Sep 17 00:00:00 2001 From: Sahitya Tummala Date: Mon, 2 May 2011 18:07:01 +0530 Subject: [PATCH] mmc: msm_sdcc: Enable SDC host->clk only after setting the rate. For clocks that support rates which can be set (most clocks other than _pclk AHB clocks), a rate must be set using clk_set_rate() before the clock is enabled for the first time with clk_enable(). Subsequent calls to clk_enable() need not be preceded with the clk_set_rate() calls unless we wish to change the clock rate that is set previously. SDC host->clk is currently enabled without setting the clock rate even once. This patch fixes this, by ensuring that the clock rate for this clock is first set before enabling the clock.
