-Subject: [PATCH] add-limit-sdcard-clk-cmdline.patch
-
-This patch allows you to control the maximum clock rate that will
-be selected for SD Card access, from the kernel commandline using
-
- glamo_mci.sd_max_clk=10000000
-
-and also from
-
- echo 10000000 > /sys/module/glamo_mci/parameters/sd_max_clk
-
-although you have to suspend and resume to make the limit operational
-on the actual SD_CLK line.
-
-Clocks that are possible are divided down from ~50MHz, so 25000000,
-16666666, 12500000, 10000000, etc.  With Freerunner A5 revision that
-has 100R series resistors in SD Card signals, I didn't get reliable
-operation above 16MHz.  With A6 revision the series resistors went
-down to 75R, maybe it can work at 25MHz.
-
-Reducing the clock rate is something to try if you find that your
-SD Card is not communicating properly with the default speed.
