Hi,
Thanks you for the test.
here a new version of the patch. It doesn't replace mdelay with jiffies
anymore. It changes mdelay to udelay (the granularity of 1 ms becomes 10
us).
I didn't mesure irq off latency with this patch.

Hi,
Not good news. This
The main problem is sdhci_send_command function. it loops at while
function infinitely.
I just modify it to use udelay at there. then it's working well.
also I reduce the granularity as 1 usec instead of 10 usec (as you suggested).
it's also works.
Thank you,

This patch is bug fixed..
I think that host-ios.clock(initial clock) will be set lower than 400KHz.
But in this code, if host-f_min is higher than 400KHz, print warning message
and set higher than 400KHz.
