* UMC (UWB Multi-interface Controller) capabilities (e.g., radio

* controller, host controller) are presented as devices on the "umc"
|

* bus.
|
||||
*
|
||||
* The radio controller is not strictly a UMC capability but it's
|
||||
* useful to present it as such.

*
|
||||
* References:
|
||||
*
|
||||
* [WHCI] Wireless Host Controller Interface Specification for
|
||||
* Certified Wireless Universal Serial Bus, revision 0.95.
|
||||
*
|
||||
* How this works is kind of convoluted but simple. The whci.ko driver
|
||||
* loads when WHCI devices are detected. These WHCI devices expose
|
||||
* many devices in the same PCI function (they couldn't have reused
|
||||
* functions, no), so for each PCI function that exposes these many
|
||||
* devices, whci ceates a umc_dev [whci_probe() -> whci_add_cap()]
|
||||
* with umc_device_create() and adds it to the bus with
|
||||
* umc_device_register().
|
||||
*
|
||||
* umc_device_register() calls device_register() which will push the
|
||||
* bus management code to load your UMC driver's somehting_probe()
|
||||
* that you have registered for that capability code.
|
||||
*
|
||||
* Now when the WHCI device is removed, whci_remove() will go over
|
||||
* each umc_dev assigned to each of the PCI function's capabilities
|
||||
* and through whci_del_cap() call umc_device_unregister() each
|
||||
* created umc_dev. Of course, if you are bound to the device, your
|
||||
* driver's something_remove() will be called.
