   4 Subject: [PATCH] usb: Make sure usb/phy/of gets built-in
   5
   6 DWC3 driver uses of_usb_get_phy_mode() which is
   7 implemented in drivers/usb/phy/of.c and in bare minimal
   8 configuration it might not be pulled in kernel binary.
   9
  10 In case of ARC or ARM this could be easily reproduced with
  11 "allnodefconfig" +CONFIG_USB=m +CONFIG_USB_DWC3=m.
  12
  13 On building all ends-up with:
  14 ---------------------->8------------------
  15   Kernel: arch/arm/boot/Image is ready
  16   Kernel: arch/arm/boot/zImage is ready
  17   Building modules, stage 2.
  18   MODPOST 5 modules
