12 * The of_device *was* a kind of "base class" that was a superset of
13 * struct device for use by devices attached to an OF node and probed
14 * using OF properties. However, the important bit of OF-style
15 * probing, namely the device node pointer, has been moved into the
16 * common struct device when CONFIG_OF is set to make OF-style probing
17 * available to all bus types. So now, just make of_device and
18 * platform_device equivalent so that current of_platform bus users
19 * can be transparently migrated over to using the platform bus.
21 * This line will go away once all references to of_device are removed
