Ben Dooks 5a2c4fe04d s3cmci: make SDIO IRQ hardware IRQ support build-time configurable
We have found a couple of boards where the SDIO IRQ hardware support has
failed to work properly, and thus we should make it configurable whether
or not to be included in the 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
tristate "Intel PXA25x/26x/27x Multimedia Card Interface support"
depends on ARCH_PXA
help
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"
depends on HAS_DMA
help
This selects 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. You
also need to enable an appropriate bus interface.
If unsure, say N.
config MMC_SDHCI_IO_ACCESSORS
bool
depends on MMC_SDHCI
help
This is silent Kconfig symbol that is selected by the drivers that
need to overwrite SDHCI IO memory accessors.
config MMC_SDHCI_PCI
tristate "SDHCI support on PCI bus"
depends on MMC_SDHCI && PCI
help
This selects the PCI Secure Digital Host Controller Interface.
Most controllers found today are PCI devices.
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 MMC_SDHCI_PCI
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_SDHCI_OF
tristate "SDHCI support on OpenFirmware platforms"
depends on MMC_SDHCI && PPC_OF
select MMC_SDHCI_IO_ACCESSORS
help
This selects the OF support for Secure Digital Host Controller
Interfaces. So far, only the Freescale eSDHC controller is known
to exist on OF platforms.
If unsure, say N.
config MMC_SDHCI_PLTFM
tristate "SDHCI support on the platform specific bus"
depends on MMC_SDHCI
help

If unsure, say N.
config MMC_SDHCI_S3C
tristate "SDHCI support on Samsung S3C SoC"
depends on MMC_SDHCI && (PLAT_S3C24XX || PLAT_S3C64XX)
help
This selects the Secure Digital Host Controller Interface (SDHCI)
often referrered to as the HSMMC block in some of the Samsung S3C
range of SoC.
Note, due to the problems with DMA, the DMA support is only
available with CONFIG_EXPERIMENTAL is selected.
If you have a controller with this interface, say Y or M here.
If unsure, say N.
config MMC_SDHCI_S3C_DMA
bool "DMA support on S3C SDHCI"
depends on MMC_SDHCI_S3C && EXPERIMENTAL
help
Enable DMA support on the Samsung S3C SDHCI glue. The DMA
has proved to be problematic if the controller encounters
certain errors, and thus should be treated with care.
YMMV.
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.

config MMC_OMAP_HS
tristate "TI OMAP High Speed Multimedia Card Interface support"
depends on ARCH_OMAP2430 || ARCH_OMAP3 || ARCH_OMAP4

This selects the TI OMAP High Speed Multimedia card Interface.
If you have an OMAP2430 or OMAP3 board or OMAP4 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"

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"

help
Choose which driver to use for the Atmel MCI Silicon
config MMC_AT91

you have an AT32 (AVR32) or AT91 platform with a Multimedia
Card slot, say Y or M here.
If unsure, say N.
endchoice
config MMC_ATMELMCI_DMA
bool "Atmel MCI DMA support (EXPERIMENTAL)"
depends on MMC_ATMELMCI && AVR32 && DMA_ENGINE && EXPERIMENTAL
help
Say Y here to have the Atmel MCI driver use a DMA engine to
do data transfers and thus increase the throughput and
reduce the CPU utilization. Note that this is highly
experimental and may cause the driver to lock up.
If unsure, say N.
config MMC_IMX
tristate "Motorola i.MX Multimedia Card Interface support"
depends on ARCH_MX1
help
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.

This selects the Freescale i.MX2/3 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_MVSDIO
tristate "Marvell MMC/SD/SDIO host driver"
depends on PLAT_ORION
---help---
This selects the Marvell SDIO host driver.
SDIO may currently be found on the Kirkwood 88F6281 and 88F6192
SoC controllers.
To compile this driver as a module, choose M here: the
module will be called mvsdio.
config MMC_SPI
tristate "MMC/SD/SDIO over SPI"
depends on SPI_MASTER && !HIGHMEM && HAS_DMA
select CRC7
select CRC_ITU_T
help
Some systems access MMC/SD/SDIO cards using a SPI controller
instead of using a "native" MMC/SD/SDIO controller. This has a
disadvantage of being relatively high overhead, but a compensating
advantage of working on many systems without dedicated MMC/SD/SDIO
controllers.
If unsure, or if your system has no SPI master driver, say N.
config MMC_S3C
tristate "Samsung S3C SD/MMC Card Interface support"
depends on ARCH_S3C2410
help
This selects a driver for the MCI interface found in
Samsung's S3C2410, S3C2412, S3C2440, S3C2442 CPUs.
If you have a board based on one of those and a MMC/SD
slot, say Y or M here.
If unsure, say N.
config MMC_S3C_HW_SDIO_IRQ

depends on MMC_S3C
help
Enable the hardware support for SDIO interrupts instead of using
the generic polling code.
choice
prompt "Samsung S3C SD/MMC transfer code"
depends on MMC_S3C
config MMC_S3C_PIO
bool "Use PIO transfers only"
help
Use PIO to transfer data between memory and the hardware.
PIO is slower than DMA as it requires CPU instructions to
move the data. This has been the traditional default for
the S3C MCI driver.
config MMC_S3C_DMA
bool "Use DMA transfers only (EXPERIMENTAL)"
depends on EXPERIMENTAL
help
Use DMA to transfer data between memory and the hardare.
Currently, the DMA support in this driver seems to not be
working properly and needs to be debugged before this
option is useful.
config MMC_S3C_PIODMA
bool "Support for both PIO and DMA (EXPERIMENTAL)"
help
Compile both the PIO and DMA transfer routines into the
driver and let the platform select at run-time which one
is best.
See notes for the DMA option.

This provides support for the SD/MMC cell found in TC6393XB,
T7L66XB and also HTC ASIC3
config MMC_CB710
tristate "ENE CB710 MMC/SD Interface support"
depends on PCI
select CB710_CORE
help
This option enables support for MMC/SD part of ENE CB710/720 Flash
memory card reader found in some laptops (ie. some versions of
HP Compaq nx9500).
This driver can also be built as a module. If so, the module
will be called cb710-mmc.
config MMC_VIA_SDMMC
