Carlo Caione ed80a13bb4 mmc: meson-mx-sdio: Add a driver for the Amlogic Meson8 and Meson8b SoCs 
Add a driver for the SDIO/MMC host found on the Amlogic Meson SoCs. This
is an MMC controller which provides an interface between the application
processor and various memory cards. It supports the SD specification
v2.0 and the eMMC specification v4.41.

The controller provides an internal "mux" which allows connecting up to
three MMC devices to it. Only one device can be used at a time though
since the registers are shared across all devices. The driver takes care
of synchronizing access (similar to the dw_mmc driver).
The maximum supported bus-width is 4-bits.

Amlogic's GPL kernel sources call the corresponding driver "aml_sdio" to
differentiate it from the other MMC controller in (at least the Meson8
and Meson8b) the SoCs (they call the other drivers aml_sdhc and
aml_sdhc_m8, which seem to support a bus-width of up to 8-bits). This
means that there are three different MMC host controller IP blocks from
Amlogic (each of them with completely own register layout and features):
- "SDIO": 1 and 4 bit bus width, support for high-speed modes up to
  UHS-I SDR50, part of Meson6, Meson8 and Meson8b (the driver from this
  patch targets this controller)
- "SDHC": 1, 4 and 8 bit bus width, compatible with standard iNAND
  interface, support for speeds up to HS200 and MMC spec up to version
  4.5x, part of Meson8 and Meson8b SoCs (there is no mainline driver
  for this controller yet)
- "SDEMMC": 1, 4 and 8 bit bus width, support for speeds up to HS400
  and MMC spec up to version 5.0, part of the Meson GX (64-bit) SoCs
  (supported by the meson-gx MMC host driver)

config MMC_DEBUG
bool "MMC host drivers debugging"

help
This is an option for use by developers; most people should
say N here. This enables MMC host driver debugging. And further
added host drivers please don't invent their private macro for
debugging.

platform with a Multimedia Card slot, say Y or M here.
If unsure, say N.

help
This selects the Qualcomm Data Mover lite/local on SD Card controller.
This option will enable the dma to work correctly, if you are using
Qcom SOCs and MMC, you would probably need this option to get DMA working.
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

This is silent Kconfig symbol that is selected by the drivers that
need to overwrite SDHCI IO memory accessors.
config MMC_SDHCI_BIG_ENDIAN_32BIT_BYTE_SWAPPER
bool
depends on MMC_SDHCI
select MMC_SDHCI_IO_ACCESSORS
help
This option is selected by drivers running on big endian hosts
and performing I/O to a SDHCI controller through a bus that
implements a hardware byte swapper using a 32-bit datum.
This endian mapping mode is called "data invariance" and
has the effect of scrambling the addresses and formats of data
accessed in sizes other than the datum size.
This is the case for the Nintendo Wii SDHCI.
config MMC_SDHCI_PCI
tristate "SDHCI support on PCI bus"

If unsure, say N.
config MMC_RICOH_MMC
bool "Ricoh MMC Controller Disabler"
depends on MMC_SDHCI_PCI
default y
help
This adds a pci quirk to disable 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 even if you don't
have a Ricoh based card reader.
If unsure, say Y.

to single and multifunction SDIO cards.
Some SDIO cards will need a firmware file to be loaded and
sent to VUB300 chip in order to achieve better data throughput.
Download these "Offload Pseudocode" from Elan Digital Systems'
web-site http://www.elandigitalsystems.com/support/downloads.php
and put them in /lib/firmware. Note that without these additional
firmware files the VUB300 chip will still function, but not at
the best obtainable data rate.
To compile this mmc host controller driver as a module,
choose M here: the module will be called vub300.
If you have a computer with an embedded VUB300 chip
or if you intend connecting a USB adapter based on a
VUB300 chip say Y or M here.
