Hi,
This patchset contains bug fixes for host descriptor dma mode.
Descriptor dma mode can't be used as the default mode since controller
does not support split transfers in this mode.
So we add a new configuration parameter which allows descriptor dma mode
to be enabled for full-speed devices only.
All patches are verified on dwc2 v3.0a with dedicated fifos and our
main test target was usb audio devices.
All patches are based on Felipe's testing/next branch.
Regards,
Gregory
