| config PWRSEQ_EMMC |
| tristate "HW reset support for eMMC" |
| default y |
| depends on OF |
| help |
| This selects Hardware reset support aka pwrseq-emmc for eMMC |
| devices. By default this option is set to y. |
| |
| This driver can also be built as a module. If so, the module |
| will be called pwrseq_emmc. |

| config PWRSEQ_SIMPLE |
| tristate "Simple HW reset support for MMC" |
| default y |
| depends on OF |
| help |
| This selects simple hardware reset support aka pwrseq-simple for MMC |
| devices. By default this option is set to y. |
| |
| This driver can also be built as a module. If so, the module |
| will be called pwrseq_simple. |

| config MMC_RING_BUFFER |
| bool "MMC_RING_BUFFER" |
| depends on MMC |
| default n |
| help |
| This enables the ring buffer tracing of significant |
| events for mmc driver to provide command history for |
| debugging purpose. |
| |
| If unsure, say N. |
| |
| config MMC_EMBEDDED_SDIO |
| boolean "MMC embedded SDIO device support (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)" |
| 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. |
| |
| 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. |
