--GPIOMMC - Driver for an MMC/SD card on a bitbanging GPIO SPI bus
--================================================================
--
--The gpiommc module hooks up the mmc_spi and spi_gpio modules for running an
--MMC or SD card on GPIO pins.
--
--Two interfaces for registering a new MMC/SD card device are provided:
--A static platform-device based mechanism and a dynamic configfs based interface.
--
--
--Registering devices via platform-device
--=======================================
--
--The platform-device interface is used for registering MMC/SD devices that are
--part of the hardware platform. This is most useful only for embedded machines
--with MMC/SD devices statically connected to the platform GPIO bus.
--
--The data structures are declared in <linux/mmc/gpiommc.h>.
--
--To register a new device, define an instance of struct gpiommc_platform_data.
--This structure holds any information about how the device is hooked up to the
--GPIO pins and what hardware modes the device supports. See the docbook-style
--documentation in the header file for more information on the struct fields.
--
--Then allocate a new instance of a platform device by doing:
--
--	pdev = platform_device_alloc(GPIOMMC_PLATDEV_NAME, gpiommc_next_id());
--
--This will allocate the platform device data structures and hook it up to the
--gpiommc driver.
--Then add the gpiommc_platform_data to the platform device.
--
--	err = platform_device_add_data(pdev, pdata, sizeof(struct gpiommc_platform_data));
--
--You may free the local instance of struct gpiommc_platform_data now. (So the
--struct may be allocated on the stack, too).
--Now simply register the platform device.
--
--	err = platform_device_add(pdev);
--
--Done. The gpiommc probe routine will be invoked now and you should see a kernel
--log message for the added device.
--
--
--Registering devices via configfs
--================================
--
--MMC/SD cards connected via GPIO often are a pretty dynamic thing, as for example
--selfmade hacks for soldering an MMC/SD card to standard GPIO pins on embedded
--hardware are a common situation.
--So we provide a dynamic interface to conveniently handle adding and removing
--devices from userspace, without the need to recompile the kernel.
--
--The "gpiommc" subdirectory at the configfs mountpoint is used for handling
--the dynamic configuration.
--
--To create a new device, it must first be allocated with mkdir.
--The following command will allocate a device named "my_mmc":
--	mkdir /config/gpiommc/my_mmc
--
--There are several configuration files available in the new
--/config/gpiommc/my_mmc/ directory:
--
--gpio_data_in			= The SPI data-IN GPIO pin number.
--gpio_data_out			= The SPI data-OUT GPIO pin number.
--gpio_clock			= The SPI Clock GPIO pin number.
--gpio_chipselect			= The SPI Chipselect GPIO pin number.
--gpio_chipselect_activelow	= Boolean. If 0, Chipselect is active-HIGH.
--				  If 1, Chipselect is active-LOW.
--spi_mode			= The SPI data mode. Can be 0-3.
--spi_delay			= Enable all delays in the lowlevel bitbanging.
--max_bus_speed			= The maximum SPI bus speed. In Hertz.
--
--register			= Not a configuration parameter.
--				  Used to register the configured card
--				  with the kernel.
--
--The device must first get configured and then registered by writing "1" to
--the "register" file.
--The configuration parameters "gpio_data_in", "gpio_data_out", "gpio_clock"
--and "gpio_chipselect" are essential and _must_ be configured before writing
--"1" to the "register" file. The registration will fail, otherwise.
--
--The default values for the other parameters are:
--gpio_chipselect_activelow	= 1		(CS active-LOW)
--spi_mode			= 0		(SPI_MODE_0)
--spi_delay			= 1		(enabled)
--max_bus_speed			= 5000000	(5 Mhz)
--
--Configuration values can not be changed after registration. To unregister
--the device, write a "0" to the "register" file. The configuration can be
--changed again after unregistering.
--
--To completely remove the device, simply rmdir the directory
--(/config/gpiommc/my_mmc in this example).
--There's no need to first unregister the device before removing it. That will
--be done automatically.
