By default this option is set to y. 11 12 This driver can also be built as a module. If so, the module 13 will be called pwrseq_emmc. 14 15config PWRSEQ_SD8787 16 tristate "HW reset support for SD8787 BT + Wifi module" 17 depends on OF && (MWIFIEX || BT_MRVL_SDIO) 18 help 19 This selects hardware reset support for the SD8787 BT + Wifi 20 module. By default this option is set to n. 21 22 This driver can also be built as a module. If so, the module 23 will be called pwrseq_sd8787. 24 25config PWRSEQ_SIMPLE 26 tristate "Simple HW reset support for MMC" 27 default y 28 depends on OF 29 help 30 This selects simple hardware reset support aka pwrseq-simple for MMC 31 devices. By default this option is set to y. 32 33 This driver can also be built as a module. If so, the module 34 will be called pwrseq_simple. 35 36config MMC_BLOCK 37 tristate "MMC block device driver" 38 depends on BLOCK 39 default y 40 help 41 Say Y here to enable the MMC block device driver support. 42 This provides a block device driver, which you can use to 43 mount the filesystem. Almost everyone wishing MMC support 44 should say Y or M here. 45 46config MMC_BLOCK_MINORS 47 int "Number of minors per block device" 48 depends on MMC_BLOCK 49 range 4 256 50 default 8 51 help 52 Number of minors per block device. One is needed for every 53 partition on the disk (plus one for the whole disk). 54 55 Number of total MMC minors available is 256, so your number 56 of supported block devices will be limited to 256 divided 57 by this number. 58 59 Default is 8 to be backwards compatible with previous 60 hardwired device numbering. 61 62 If unsure, say 8 here. 63 64config SDIO_UART 65 tristate "SDIO UART/GPS class support" 66 depends on TTY 67 help 68 SDIO function driver for SDIO cards that implements the UART 69 class, as well as the GPS class which appears like a UART. 70 71config MMC_TEST 72 tristate "MMC host test driver" 73 help 74 Development driver that performs a series of reads and writes 75 to a memory card in order to expose certain well known bugs 76 in host controllers. The tests are executed by writing to the 77 "test" file in debugfs under each card. Note that whatever is 78 on your card will be overwritten by these tests. 79 80 This driver is only of interest to those developing or 81 testing a host driver. Most people should say N here. 82 83config MMC_EMBEDDED_SDIO 84 boolean "MMC embedded SDIO device support" 85 help 86 If you say Y here, support will be added for embedded SDIO 87 devices which do not contain the necessary enumeration 88 support in hardware to be properly detected. 89 90config MMC_PARANOID_SD_INIT 91 bool "Enable paranoid SD card initialization" 92 help 93 If you say Y here, the MMC layer will be extra paranoid 94 about re-trying SD init requests. This can be a useful 95 work-around for buggy controllers and hardware. Enable 96 if you are experiencing issues with SD detection. 97
