NAME¶
superhyway_add_device - Add a SuperHyway moduleSYNOPSIS¶
int
superhyway_add_device(unsigned long base,
struct superhyway_device * sdev,
struct superhyway_bus * bus);
ARGUMENTS¶
basePhysical address where module is mapped.
sdev
SuperHyway device to add, or NULL to allocate a new
one.
bus
Bus where SuperHyway module resides.
DESCRIPTION¶
This is responsible for adding a new SuperHyway module. This sets up a new struct superhyway_device for the module being added if sdev == 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.AUTHOR¶
