The CONFIG_EXPERIMENTAL config item has not carried much meaning for a while now and is almost always enabled by default. As agreed during the Linux kernel summit, remove it from any "depends on" lines in Kconfigs.

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".

bool "MMC host clock gating"
|
|
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.
