From b9af55ba5d55041efbf5155b58c90d2fb8dc00d0 Mon Sep 17 00:00:00 2001 From: Alexey Brodkin Date: Thu, 13 Apr 2017 15:33:34 +0300 Subject: [PATCH] usb: Make sure usb/phy/of gets built-in BugLink: http://bugs.launchpad.net/bugs/1692898 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.
