I have a branch that's based on 4.17. You can pick that.
https://github.com/vivekgautam1/linux/commits/v4.17/db820c

Thanks a lot,
I will test this branch.

I just tested USB gadget with this branch on the db820c.

If I activate a USB composite gadget device with EEM function, I can see
the 'usb0' Ethernet interfaces on the device and on the host and I can ping
the db820c from the host.
When I create a USB composite gadget device with UAC2 function, I can see
the audio cards on host and device but cannot play or record any sound.

While looking at dwc3 traces with Ftrace, I noticed that the dwc3 driver is
stuck on wait_event_lock_irq() in dwc3_gadget_ep_dequeue() function when I
use UAC2 gadget.

can you share tracepoint data?

you need to talk to your company's IT about removing this footer. This
makes the life of those maintaining mailing list archives rather
difficult.
