[PATCH V3 3/4] mmc: mmci: Adapt to register write restrictions

2013-09-03 Thread Ulf Hansson
After a write to the MMCICLOCK register data cannot be written to this register for three feedback clock cycles. Writes to the MMCIPOWER register must be separated by three MCLK cycles. Previously no issues has been observered, but using higher ARM clock frequencies on STE- platforms has triggered
