# # MMC core configuration # 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_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.
