This was caused by omitting, that SDHCI driver for Exynos 4, calls get_mmc_clk(), with mmc device number as argument, instead of pinmux peripheral id, like DW MMC driver for Exynos 5. By this commit, the code directly calls a proper function to get mmc clock for Exynos 4, without checking the peripheral id. Tested on: Odroid U3/X2, Trats, Trats2, Odroid XU3, Snow (by Simon).
