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_SD8787
tristate "HW reset support for SD8787 BT + Wifi module"
depends on OF && (MWIFIEX != n || BT_MRVL_SDIO != n || LIBERTAS_SDIO != n || WILC1000_SDIO != n)
help
This selects hardware reset support for the SD8787 BT + Wifi
module. By default this option is set to n.
This driver can also be built as a module. If so, the module
will be called pwrseq_sd8787.
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_BLOCK
tristate "MMC block device driver"
depends on BLOCK
depends on RPMB || !RPMB
imply IOSCHED_BFQ
default y
help
Say Y here to enable the MMC block device driver support.
This provides a block device driver, which you can use to
mount the filesystem. Almost everyone wishing MMC support
should say Y or M here.
config MMC_BLOCK_MINORS
int "Number of minors per block device"
depends on MMC_BLOCK
range 4 256
default 8
help
Number of minors per block device. One is needed for every
partition on the disk (plus one for the whole disk).
Number of total MMC minors available is 256, so your number
of supported block devices will be limited to 256 divided
by this number.
Default is 8 to be backwards compatible with previous
hardwired device numbering.
If unsure, say 8 here.
config SDIO_UART
tristate "SDIO UART/GPS class support"
depends on TTY
help
SDIO function driver for SDIO cards that implements the UART
class, as well as the GPS class which appears like a UART.
config MMC_TEST
tristate "MMC host test driver"
help
Development driver that performs a series of reads and writes
to a memory card in order to expose certain well known bugs
in host controllers. The tests are executed by writing to the
"test" file in debugfs under each card. Note that whatever is
on your card will be overwritten by these tests.
This driver is only of interest to those developing or
testing a host driver. Most people should say N here.
config MMC_CRYPTO
bool "MMC Crypto Engine Support"
depends on BLK_INLINE_ENCRYPTION
help
Enable Crypto Engine Support in MMC.
Enabling this makes it possible for the kernel to use the crypto
capabilities of the MMC device (if present) to perform crypto
operations on data being transferred to/from the device.
