-/* Using qdev pointer properties for the clocks is not ideal.
- * qdev should support a generic means of defining a 'port' with
- * an arbitrary interface for connecting two devices. Then we
- * could reframe the omap clock API in terms of clock ports,
- * and get some type safety. For now the best qdev provides is
- * passing an arbitrary pointer.
- * (It's not possible to pass in the string which is the clock
- * name, because this device does not have the necessary information
- * (ie the struct omap_mpu_state_s*) to do the clockname to pointer
- * translation.)
