[PATCH 03/13] mmc: dw_mmc: change the DW_MCI_FREQ_MIN from 400K to 100K

From: Jaehoon Chung
Date: Thu Nov 03 2016 - 02:24:03 EST


If there is no property "clock-freq-min-max", mmc->f_min should be set
to 400K by default. But Some SoC can be used 100K.
When 100K is used, MMC core will try to check from 400K to 100K.
