23 | * of_platform_driver - Legacy of-aware driver for platform devices. | |
24 | * | |
25 | * An of_platform_driver driver is attached to a basic platform_device on | |
26 | * ether the "platform bus" (platform_bus_type), or the ibm ebus | |
27 | * (ibmebus_bus_type). | |
28 | * | |
29 | * of_platform_driver is being phased out when used with the platform_bus_type, | |
30 | * and regular platform_drivers should be used instead. When the transition | |
31 | * is complete, only ibmebus will be using this structure, and the | |
32 | * platform_driver member of this structure will be removed. | |
