-Subject: [PATCH 0160/1002] usb: add plumbing for updating interrupt endpoint
- interval state
-
-xHCI caches device and endpoint data after the interface is configured,
-so an explicit command needs to be issued for any device driver wanting
-to alter the polling interval of an endpoint.
-
-Add usb_fixup_endpoint() to allow drivers to do this. The fixup must be
-called after calculating endpoint bandwidth requirements but before any
-URBs are submitted.
-
-If polling intervals are shortened, any bandwidth reservations are no
-longer valid but in practice polling intervals are only ever relaxed.
-
-Limit the scope to interrupt transfers for now.
-
