SUPERHYWAY_ADD_DEVIC(9)                       Busses                      SUPERHYWAY_ADD_DEVIC(9)



NAME
       superhyway_add_device - Add a SuperHyway module

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

ARGUMENTS
       base
           Physical 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.
