-	All this does is walk through all SBUS devices in the
-system, checks each to see if it is of the type which
-your driver is written for, and if so it calls the init
-routine to attach the device and prepare to drive it.

+		},
+		{},

+	MODULE_DEVICE_TABLE(of, mydevice_match);
 
-	"init_one_mydevice" might do things like allocate software
-state structures, map in I/O registers, place the hardware
-into an initialized state, etc.
+	static struct of_platform_driver mydevice_driver = {
+		.name		= "mydevice",

+
+	The mydevice_match table is a series of entries which
+describes what SBUS devices your driver is meant for.  In the
+simplest case you specify a string for the 'name' field.  Every
+SBUS device with a 'name' property matching your string will
+be passed one-by-one to your .probe method.
+
+	You should store away your device private state structure
+pointer in the drvdata area so that you can retrieve it later on
+in your .remove method.
+
+	Any memory allocated, registers mapped, IRQs registered,
+etc. must be undone by your .remove method so that all resources
+of your device are relased by the time it returns.
+
+	You should _NOT_ use the for_each_sbus(), for_each_sbusdev(),
+and for_all_sbusdev() interfaces.  They are deprecated, will be
+removed, and no new driver should reference them ever.
