IOResourceMatch
One or more system-specific or device-specific resources that your driver requires.
Discussion
The value of this key is a string or an array of strings. Each string contains the name of a resource that must be published in the global resource list before the system loads the driver. For example, specify IOBSD to prevent the system from loading your driver until after the BSD kernel is available.
To access the list of global resources, call the getResourceService method of IOService. To publish custom resources from your driver, call the publishResource method.
