> Betreff: [PATCH 03/11] usb: xhci: add quirks flag to support MediaTek xHCI
> 0.96
>
> There some vendor quirks for MTK xHCI 0.96 host controller:
> 1. It defines some extra SW scheduling parameters for HW
> to minimize the scheduling effort for synchronous and
> interrupt endpoints. The parameters are put into reseved
> DWs of slot context and endpoint context.
> 2. Its TDS in Normal TRB defines a number of packets that
> remains to be transferred for a TD after processing all
> Max packets in all previous TRBs.
Tested full series on Bananapi-R2 and R64 (can post DTS-nodes later or can be
found here [1])
