| Subject: usb: Make sure usb/phy/of gets built-in |
| |
| From: Alexey Brodkin <Alexey.Brodkin@synopsys.com> |
| |
| commit 3d6159640da9c9175d1ca42f151fc1a14caded59 upstream. |
| |
| 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------------------ |
