Subject: tmio_mmc: use 100ms mmc_detect_change() delay
From: Magnus Damm <damm@xxxxxxxxxxxxx>
Change the tmio_mmc driver to wait 100ms before checking the card detect
status. This type of delay is quite common among mmc drivers, it seems
that most hardware platforms need to give the hardware some time to settle
before checking card availabilty.
Hotplug is half-broken without this patch on the sh7724 Ecovec board. Hot
plugging seems ok but eject is never detected without this patch.
