-Subject: [PATCH] usb: dwc2: use a longer core rest timeout in
- dwc2_core_reset()
-
-Testing on different generations of Lantiq MIPS SoC based boards, showed
-that it takes up to 1500 us until the core reset bit is cleared.
-
-The driver from the vendor SDK (ifxhcd) uses a 1 second timeout. Use the
-same timeout to fix wrong hang detections and make the driver work for
-Lantiq MIPS SoCs.
