+Subject: [PATCH] usb: Make sure usb/phy/of gets built-in
+
+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:
+---------------------->8------------------
+ 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
+---------------------->8------------------
