    usb: Make sure usb/phy/of gets built-in · 3d615964
    Alexey Brodkin authored
    DWC3 driver uses of_usb_get_phy_mode() which is
    implemented in drivers/usb/phy/of.c and in bare minimal
    configuration it might not be pulled in kernel binary.
    In case of ARC or ARM this could be easily reproduced with
    "allnodefconfig" +CONFIG_USB=m +CONFIG_USB_DWC3=m.
    On building all ends-up with:
      Kernel: arch/arm/boot/Image is ready
      Kernel: arch/arm/boot/zImage is ready
      Building modules, stage 2.
      MODPOST 5 modules
    ERROR: "of_usb_get_phy_mode" [drivers/usb/dwc3/dwc3.ko] undefined!
    make[1]: *** [__modpost] Error 1
    make: *** [modules] Error 2
