| 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. | ||
| 13 | * | ||

| 15 | * from the kernel. | ||
