   6        bool "Assume MMC/SD cards are non-removable (DANGEROUS)"
   7        help
   8          If you say Y here, the MMC layer will assume that all cards
   9          stayed in their respective slots during the suspend. The
  10          normal behaviour is to remove them at suspend and
  11          redetecting them at resume. Breaking this assumption will
  12          in most cases result in data corruption.
  13
  14          This option is usually just for embedded systems which use
  15          a MMC/SD card for rootfs. Most people should say N here.
  16
  17          This option sets a default which can be overridden by the
  18          module parameter "removable=0" or "removable=1".

  20config MMC_CLKGATE
  21        bool "MMC host clock gating"
  22        help
  23          This will attempt to aggressively gate the clock to the MMC card.
  24          This is done to save power due to gating off the logic and bus
  25          noise when the MMC card is not in use. Your host driver has to
  26          support handling this in order for it to be of any use.
  27
  28          If unsure, say N.
