+ * register tables with the known events and their sizes, and then we
+ * traverse those tables. For those with variable length, we provide a
+ * way to lookup the size inside the event/notification's
+ * payload. This allows device-specific event size tables to be
+ * registered.
+ *
+ * @size:   Size of the payload

+ * @offset: if != 0, at offset @offset-1 starts a field with a length

+ *
+ * This file is released under the GPLv2
+ *
+ * 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.
