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
