From 89a9cc47513e91bc91ba2c438d5e422a0c8d05e7 Mon Sep 17 00:00:00 2001 From: Thinh Nguyen Date: Fri, 2 Nov 2018 18:41:42 -0700 Subject: [PATCH] usb: dwc3: Set default mode for DWC_usb3 v3.30a and higher DWC_usb31 and DWC_usb3 v3.30a and higher do not support OTG mode. If the controller supports DRD but the dr_mode is not specified or set to OTG, then set the mode to peripheral.
