Several Cadence3 improvements are introduced in v5.13-rc1:
- Add recovery during resume if the controller was lost power at system suspend
- Reduce DMA memory footprint
- Other small improvements
usb: cdnsp: Fixes issue with Configure Endpoint command
Patch adds flag EP_UNCONFIGURED to detect whether endpoint was
unconfigured. This flag is set in cdnsp_reset_device after Reset Device
command. Among others this command disables all non control endpoints.
Flag is used in cdnsp_gadget_ep_disable to protect controller against
invoking Configure Endpoint command on disabled endpoint. Lack of this
protection in some cases caused that Configure Endpoint command completed
with Context State Error code completion.
