5config PWRSEQ_EMMC
6 tristate "HW reset support for eMMC"
7 default y
8 depends on OF
9 help
10 This selects Hardware reset support aka pwrseq-emmc for eMMC
11 devices. By default this option is set to y.
12
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 || BT_MRVL_SDIO || LIBERTAS_SDIO || WILC1000_SDIO)
19 help
20 This selects hardware reset support for the SD8787 BT + Wifi
21 module. By default this option is set to n.
22
23 This driver can also be built as a module. If so, the module
24 will be called pwrseq_sd8787.

29 depends on OF
30 help
31 This selects simple hardware reset support aka pwrseq-simple for MMC
32 devices. By default this option is set to y.
33
34 This driver can also be built as a module. If so, the module
35 will be called pwrseq_simple.

37config MMC_BLOCK
38 tristate "MMC block device driver"
39 depends on BLOCK
40 default y
41 help
42 Say Y here to enable the MMC block device driver support.
43 This provides a block device driver, which you can use to
44 mount the filesystem. Almost everyone wishing MMC support
45 should say Y or M here.
46
47config MMC_BLOCK_MINORS
48 int "Number of minors per block device"
49 depends on MMC_BLOCK
50 range 4 256
51 default 8
52 help
53 Number of minors per block device. One is needed for every
54 partition on the disk (plus one for the whole disk).
55
56 Number of total MMC minors available is 256, so your number
57 of supported block devices will be limited to 256 divided
58 by this number.
59
60 Default is 8 to be backwards compatible with previous
61 hardwired device numbering.
62
63 If unsure, say 8 here.

65config SDIO_UART
66 tristate "SDIO UART/GPS class support"
67 depends on TTY
68 help
69 SDIO function driver for SDIO cards that implements the UART
70 class, as well as the GPS class which appears like a UART.
71
72config MMC_TEST
73 tristate "MMC host test driver"
74 help
75 Development driver that performs a series of reads and writes
76 to a memory card in order to expose certain well known bugs
77 in host controllers. The tests are executed by writing to the
78 "test" file in debugfs under each card. Note that whatever is
79 on your card will be overwritten by these tests.
80
81 This driver is only of interest to those developing or
82 testing a host driver. Most people should say N here.
83
84config MMC_CRYPTO
85 bool "MMC Crypto Engine Support"
86 depends on BLK_INLINE_ENCRYPTION
87 help
88 Enable Crypto Engine Support in MMC.
89 Enabling this makes it possible for the kernel to use the crypto
90 capabilities of the MMC device (if present) to perform crypto
91 operations on data being transferred to/from the device.
