6 tristate "HW reset support for eMMC"
10 This selects Hardware reset support aka pwrseq-emmc for eMMC
11 devices. By default this option is set to y.
13 This driver can also be built as a module. If so, the module
14 will be called pwrseq_emmc.
17 tristate "HW reset support for SD8787 BT + Wifi module"
18 depends on OF && (MWIFIEX != n || BT_MRVL_SDIO != n || LIBERTAS_SDIO != n || WILC1000_SDIO != n)
20 This selects hardware reset support for the SD8787 BT + Wifi
21 module. By default this option is set to n.
23 This driver can also be built as a module. If so, the module
24 will be called pwrseq_sd8787.
27 tristate "Simple HW reset support for MMC"
31 This selects simple hardware reset support aka pwrseq-simple for MMC
32 devices. By default this option is set to y.
34 This driver can also be built as a module. If so, the module
35 will be called pwrseq_simple.
38 tristate "MMC block device driver"
40 depends on RPMB || !RPMB
44 Say Y here to enable the MMC block device driver support.
45 This provides a block device driver, which you can use to
46 mount the filesystem. Almost everyone wishing MMC support
47 should say Y or M here.
49 config MMC_BLOCK_MINORS
50 int "Number of minors per block device"
55 Number of minors per block device. One is needed for every
56 partition on the disk (plus one for the whole disk).
58 Number of total MMC minors available is 256, so your number
59 of supported block devices will be limited to 256 divided
62 Default is 8 to be backwards compatible with previous
63 hardwired device numbering.
65 If unsure, say 8 here.
68 tristate "SDIO UART/GPS class support"
71 SDIO function driver for SDIO cards that implements the UART
72 class, as well as the GPS class which appears like a UART.
75 tristate "MMC host test driver"
77 Development driver that performs a series of reads and writes
78 to a memory card in order to expose certain well known bugs
79 in host controllers. The tests are executed by writing to the
80 "test" file in debugfs under each card. Note that whatever is
81 on your card will be overwritten by these tests.
83 This driver is only of interest to those developing or
84 testing a host driver. Most people should say N here.
87 bool "MMC Crypto Engine Support"
88 depends on BLK_INLINE_ENCRYPTION
90 Enable Crypto Engine Support in MMC.
91 Enabling this makes it possible for the kernel to use the crypto
92 capabilities of the MMC device (if present) to perform crypto
93 operations on data being transferred to/from the device.
