+Registering an auxiliary_device is a three-step process.
+
+First, a 'struct auxiliary_device' needs to be defined or allocated for each
+sub-device desired.  The name, id, dev.release, and dev.parent fields of this
+structure must be filled in as follows.
+
+The 'name' field is to be given a name that is recognized by the auxiliary
+driver.  If two auxiliary_devices with the same match_name, eg
+"mod.MY_DEVICE_NAME", are registered onto the bus, they must have unique id
+values (e.g. "x" and "y") so that the registered devices names are "mod.foo.x"
+and "mod.foo.y".  If match_name + id are not unique, then the device_add fails
+and generates an error message.
