Subject: [PATCH] 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.
