Hi Mark/Takashi,

Would it be possible to see if we could start pulling some of these non offloading dependent changes into your repos? It would really be helpful since the # of patches is getting a little cumbersome to maintain. If we need to make any follow ups, I can address them as a separate patch and add it to the series w/ the other changes that are still pending.

Mathias Nyman (13):
xhci: fix possible null pointer dereference at secondary interrupter
removal
xhci: fix off by one check when adding a secondary interrupter.
xhci: Add interrupt pending autoclear flag to each interrupter
xhci: Add helper to set an interrupters interrupt moderation interval
xhci: make isoc_bei_interval variable interrupter specific.
xhci: remove unnecessary event_ring_deq parameter from
xhci_handle_event()
xhci: update event ring dequeue pointer position to controller
correctly
xhci: move event processing for one interrupter to a separate function
xhci: add helper that checks for unhandled events on a event ring
xhci: Don't check if the event ring is valid before every event TRB
xhci: Decouple handling an event from checking for unhandled events
xhci: add helper to stop endpoint and wait for completion
xhci: sideband: add initial api to register a sideband entity

Will work with Mathias on the XHCI stuff when he gets some time to review the set of changes added for the XHCI interrupters. Some of the series in USB SND are dependent on that, such as the qc_audio_offload driver, since it makes calls into the XHCI sideband that was added, so won't be able to pull that in yet. (This is the only driver that will interact w/ XHCI sideband, all ASoC and general USB SND changes are independent)

Thanks
Wesley Cheng
