# MMC core configuration
bool "Assume MMC/SD cards are non-removable (DANGEROUS)"
If you say Y here, the MMC layer will assume that all cards
stayed in their respective slots during the suspend. The
normal behaviour is to remove them at suspend and
redetecting them at resume. Breaking this assumption will
in most cases result in data corruption.
This option is usually just for embedded systems which use
a MMC/SD card for rootfs. Most people should say N here.
This option sets a default which can be overridden by the
module parameter "removable=0" or "removable=1".
bool "MMC host clock gating"
This will attempt to aggressively gate the clock to the MMC card.
This is done to save power due to gating off the logic and bus
noise when the MMC card is not in use. Your host driver has to
support handling this in order for it to be of any use.
If unsure, say N.
