- 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.
