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