   4 Subject: [PATCH] usb: dwc3: gadget: increase timeout value for send ep cmd
   5
   6 In case the USB3 PHY enters P3, then ep command may need a long
   7 time to complete, per test of ep0out enable, the dwc3 trace time
   8 stamp shows the time is more then 280us, so increase the timeout
   9 loop count to be 2000, this has no side effect for HW which has
  10 no this problem.
