| 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" | |
| 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. |
