- * System devices follow a slightly different driver model. 
- * They don't need to do dynammic driver binding, can't be probed, 
- * and don't reside on any type of peripheral bus. 
- * So, we represent and treat them a little differently.
- * 
- * We still have a notion of a driver for a system device, because we still
- * want to perform basic operations on these devices. 
- *
- * We also support auxiliary drivers binding to devices of a certain class.
- * 
- * This allows configurable drivers to register themselves for devices of
- * a certain type. And, it allows class definitions to reside in generic
- * code while arch-specific code can register specific drivers.
- *
- * Auxiliary drivers registered with a NULL cls are registered as drivers
- * for all system devices, and get notification calls for each device.
