Subject: [PATCH] xhci: quirks: add link TRB quirk for VL805
|
|
|
|
The VL805 controller can't cope with the TR Dequeue Pointer for an endpoint
|
|
being set to a Link TRB. The hardware-maintained endpoint context ends up
|
|
stuck at the address of the Link TRB, leading to erroneous ring expansion
|
|
events whenever the enqueue pointer wraps to the dequeue position.
|
|
|
|
If the search for the end of the current TD and ring cycle state lands on
|
|
a Link TRB, move to the next segment.
|
|
|
|
