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