++The Expansion Interface (EXI)
++-----------------------------
++
++[Introductory information goes here...]
++
++
++Device drivers
++--------------
++
++Outlined below is the recommended practice when writing EXI device drivers.
++
++The bus driver already handles quite an amount of stuff, although some of
++it might have to be implemented by individual device drivers. If in doubt,
++see include/linux/exi.h.
++
++
++Registration
++------------
++
++Declare a struct exi_driver. Initialize at least the name, id_table,
++probe and remove fields:
++
++
++	static struct exi_device_id frob_id_tbl[] __devinitdata = {
++		{ .dev_id = EXI_ID_FROB0, },
++		{ .dev_id = EXI_ID_FROB1, },
++		{ .dev_id = EXI_ID_FROB2, },
++	};
++
++	static struct exi_driver frob_driver = {
++		.name		= "frob",
++		.id_table	= frob_id_tbl,
++		.probe		= frob_probe,
++		.remove		= __devexit_p(frob_remove),
++	};
++
++
++`name' distinguishes the driver from others registered with the bus.
++It should be short, unique, yet remain informative.
++
++`id_table' is a pointer to a table of device IDs the driver claims to
++support. These should be taken directly from include/linux/exi_ids.h.
++This table should be marked __devinitdata.
++
++`probe' is a pointer to a function that's called once the driver is bound
++to a device it claims to support. This should be marked __devinit.
++
++`remove' is a pointer to a function that's called when either the driver
++unregisters with the bus, or a device bound to that specific driver is
++physically unplugged from the bus. This should be marked __devexit and
++created with __devexit_p().
++
++From within the driver's initialization function, register the driver with
++the bus by calling exi_driver_register() with the driver structure declared
++previously:
++
++	static int __init frob_init(void)
++	{
++		return exi_driver_register(&frob_driver);
++	}
++
++
++Deregistration
++--------------
++
++If the driver may be compiled as a loadable kernel module, then all you
++have to do is call exi_driver_unregister() in the driver's exit function:
++
++	static void __exit frob_exit(void)
++	{
++		exi_driver_unregister(&frob_driver);
++	}
++
++Device Private Data
++-------------------
++
++The functions exi_set_drvdata()/exi_get_drvdata() are available for the
++sole purpose of setting and getting driver private data for an EXI device.
++These are simply helpers around the driver-model functions that do the
++actual work. Use them. That way, you don't have to worry (or worry less)
++about changes to the driver-model API.

++	 * situation by writing all 1s to the DATA register before reading
++	 * (this is indeed automatically done by the EXI layer).
++	 * But we simply can't do that when using EXI DMA transfers (these
++	 * kind of transfers do not allow bidirectional operation).

++ * 	take			yes
++ * 	give			yes
++ * 	select			yes
++ * 	deselect		yes
++ * 	transfer		yes/no (1)
++ *
++ * These primitives are encapsulated in several APIs.
++ * See include/linux/exi.h for additional information.
++ *
++ * 1. Kernel Contexts
++ *
++ * User, softirq and hardirq contexts are supported, with some limitations.
++ *
++ * Launching EXI operations in softirq or hardirq context requires kernel
++ * coordination to ensure channels are free before use.
++ *
++ * The EXI Layer Event System delivers events in softirq context, but it already
++ * makes provisions to ensure that channels are useable by the event handlers.
++ * Events are delivered only when the channels on the event handler
++ * channel mask are all deselected. This allows one to run EXI commands in
++ * softirq context from the EXI event handlers.
++ *
++ * "take" operations in user context will sleep if necessary until the
++ * channel is "given".
++ *
++ *
++ * 2. Transfers
++ *
++ * The EXI Layer provides a transfer API to perform read and write
++ * operations.
++ * By default, transfers partially or totally suitable for DMA will be
++ * partially or totally processed through DMA. The EXI Layer takes care of
++ * splitting a transfer in several pieces so the best transfer method is
++ * used each time.
++ *
++ * (1) A immediate mode transfer is atomic, but a DMA transfer is not.
