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