| 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. |
