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.
