[PATCH 2/4] mmci: adjust calculation of f_min

2011-06-28 Thread Linus Walleij
From: Ulf Hansson For the st_clkdiv variant f_min is too low for practical cases, there is a heuristic calculation that appear to set the min frequency to mclk rounded up with 512, for our practical use cases dividing by 257 gives a reasonable floor value on the ST Micro version of the clock divi
