Hi,
My proto board does not have a mmc card detect line to the mmc controller.
So, I have to insert the card before i insmod the mmc drivers.
If i change a card i have to rmmod and insmod the driver.
I would like to know is there anyway i can make mmc to free up all the
resources for the removed card. entries and reinitialise the new
card inserted if any
without rmmod or insmod.
I thought of using mmc_remove_host and mmc_add_host in the driver
which could be triggered by
an application through sysfs entry.
Are the calls mmc_remove_host and mmc_add_host the correct call to
use in this case?
Regards,
shri

Let the driver call mmc_detect_change() on a timer. See mmci.c for an
example.
