   8 commit 3d6159640da9c9175d1ca42f151fc1a14caded59 upstream.
   9
  10 DWC3 driver uses of_usb_get_phy_mode() which is
  11 implemented in drivers/usb/phy/of.c and in bare minimal
  12 configuration it might not be pulled in kernel binary.
  13
  14 In case of ARC or ARM this could be easily reproduced with
  15 "allnodefconfig" +CONFIG_USB=m +CONFIG_USB_DWC3=m.
  16
  17 On building all ends-up with:
  18 ---------------------->8------------------
