Function Documentation

int superhyway_add_device	(	unsigned long	base,
		struct superhyway_device *	sdev,
		struct superhyway_bus *	bus
	)

superhyway_add_device - Add a SuperHyway module : Physical address where module is mapped. : SuperHyway device to add, or NULL to allocate a new one. : Bus where SuperHyway module resides.

This is responsible for adding a new SuperHyway module. This sets up a new struct superhyway_device for the module being added if == NULL.

Devices are initially added in the order that they are scanned (from the top-down of the memory map), and are assigned an ID based on the order that they are added. Any manual addition of a module will thus get the ID after the devices already discovered regardless of where it resides in memory.

Further work can and should be done in superhyway_scan_bus(), to be sure that any new modules are properly discovered and subsequently registered.

)

superhyway_register_driver - Register a new SuperHyway driver : SuperHyway driver to register.

This registers the passed in . Any devices matching the id table will automatically be populated and handed off to the driver's specified probe routine.

void superhyway_unregister_driver

(

struct superhyway_driver *

drv

)

superhyway_unregister_driver - Unregister a SuperHyway driver : SuperHyway driver to unregister.

This cleans up after superhyway_register_driver(), and should be invoked in the exit path of any module drivers.
