(pending > issue where SMMU fault occurs if DMA addr returned is 64b - TODO) > > - Clean up pending events in the XHCI secondary interrupter. While testing USB > bus suspend, it was seen that on bus resume, the xHCI HC would run into a command > timeout. > - Added offloading APIs to xHCI to fetch transfer and event ring information. > > ASoC: > - Modified soc-usb to allow for multiple USB port additions. For this to work, > the USB offload driver has to have a reference to the USB backend by adding > a "usb-soc-be" DT entry to the device saved into XHCI sysdev. Could you tip point to where the usb-soc-be DT entry is added? > - Created separate dt-bindings for defining USB_RX port. > - Increased APR timeout to accommodate the situation where the AFE port start > command could be delayed due to having to issue a USB bus resume while > handling the QMI stream start command.
