# MMC core configuration
#
config MMC_UNSAFE_RESUME
bool "Assume MMC/SD cards are non-removable (DANGEROUS)"
help
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".
config MMC_CLKGATE
bool "MMC host clock gating (EXPERIMENTAL)"
depends on EXPERIMENTAL
help
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.
config MMC_EMBEDDED_SDIO
boolean "MMC embedded SDIO device support (EXPERIMENTAL)"
depends on EXPERIMENTAL
help
If you say Y here, support will be added for embedded SDIO
devices which do not contain the necessary enumeration
support in hardware to be properly detected.
config MMC_PARANOID_SD_INIT
bool "Enable paranoid SD card initialization (EXPERIMENTAL)"
depends on EXPERIMENTAL
help
If you say Y here, the MMC layer will be extra paranoid
about re-trying SD init requests. This can be a useful
work-around for buggy controllers and hardware. Enable
if you are experiencing issues with SD detection.
config MMC_SAMSUNG_SMART
bool "Make Samsung Smart Report available in sysfs"
help
If you say Y here, code will be added to retrieve the Smart
Report from Samsung e-MMC cards and make it available via sysfs.
