Philip Langdale 5ae70296c8 mmc: Disabler for Ricoh MMC controller
Thanks to Matt Domsch and Rezwanul Kabir at Dell, we know how to disable the
MMC controller on the multi-function Ricoh R5C832. The MMC controller needs
to be disabled or it will steal MMC cards from the SD controller where they
would otherwise be supported by the Linux SDHCI driver.

config MMC_ARMMMCI
tristate "ARM AMBA Multimedia Card Interface support"
depends on ARM_AMBA
help
This selects the ARM(R) AMBA(R) PrimeCell Multimedia Card
Interface (PL180 and PL181) support. If you have an ARM(R)
platform with a Multimedia Card slot, say Y or M here.
If unsure, say N.
config MMC_PXA

This selects the Intel(R) PXA(R) Multimedia card Interface.
If you have a PXA(R) platform with a Multimedia Card slot,
say Y or M here.
If unsure, say N.
config MMC_SDHCI
tristate "Secure Digital Host Controller Interface support (EXPERIMENTAL)"
depends on PCI && EXPERIMENTAL
help
This select the generic Secure Digital Host Controller Interface.
It is used by manufacturers such as Texas Instruments(R), Ricoh(R)
and Toshiba(R). Most controllers found in laptops are of this type.
If you have a controller with this interface, say Y or M here.
If unsure, say N.
config MMC_RICOH_MMC
tristate "Ricoh MMC Controller Disabler (EXPERIMENTAL)"
depends on PCI && EXPERIMENTAL && MMC_SDHCI
help
This selects the disabler for the Ricoh MMC Controller. This
proprietary controller is unnecessary because the SDHCI driver
supports MMC cards on the SD controller, but if it is not
disabled, it will steal the MMC cards away - rendering them
useless. It is safe to select this driver even if you don't
have a Ricoh based card reader.
To compile this driver as a module, choose M here:
the module will be called ricoh_mmc.
If unsure, say Y.
config MMC_OMAP
tristate "TI OMAP Multimedia Card Interface support"
depends on ARCH_OMAP
select TPS65010 if MACH_OMAP_H2
help
This selects the TI OMAP Multimedia card Interface.
If you have an OMAP board with a Multimedia Card slot,
say Y or M here.
If unsure, say N.
config MMC_WBSD
tristate "Winbond W83L51xD SD/MMC Card Interface support"
depends on ISA_DMA_API
help
This selects the Winbond(R) W83L51xD Secure digital and
Multimedia card Interface.
If you have a machine with a integrated W83L518D or W83L519D
SD/MMC card reader, say Y or M here.
If unsure, say N.
config MMC_AU1X
tristate "Alchemy AU1XX0 MMC Card Interface support"
depends on SOC_AU1200
help
This selects the AMD Alchemy(R) Multimedia card interface.
If you have a Alchemy platform with a MMC slot, say Y or M here.
If unsure, say N.

This selects the AT91 MCI controller.
If unsure, say N.
config MMC_IMX
tristate "Motorola i.MX Multimedia Card Interface support"

This selects the Motorola i.MX Multimedia card Interface.
If you have a i.MX platform with a Multimedia Card slot,
say Y or M here.
If unsure, say N.
config MMC_TIFM_SD
tristate "TI Flash Media MMC/SD Interface support (EXPERIMENTAL)"
depends on EXPERIMENTAL && PCI
select TIFM_CORE
help
Say Y here if you want to be able to access MMC/SD cards with
the Texas Instruments(R) Flash Media card reader, found in many
laptops.
This option 'selects' (turns on, enables) 'TIFM_CORE', but you
probably also need appropriate card reader host adapter, such as
'Misc devices: TI Flash Media PCI74xx/PCI76xx host adapter support
(TIFM_7XX1)'.
To compile this driver as a module, choose M here: the
module will be called tifm_sd.
config MMC_SPI
tristate "MMC/SD over SPI (EXPERIMENTAL)"
depends on MMC && SPI_MASTER && !HIGHMEM && EXPERIMENTAL
select CRC7
select CRC_ITU_T
help
Some systems accss MMC/SD cards using a SPI controller instead of
using a "native" MMC/SD controller. This has a disadvantage of
being relatively high overhead, but a compensating advantage of
working on many systems without dedicated MMC/SD controllers.
If unsure, or if your system has no SPI master driver, say N.
