From: Randy Dunlap rdunlap@infradead.org

[ Upstream commit c9d24f78268be444e803fb2bb138a2f598de9c23 ]

PHY drivers can use ULPI interfaces when CONFIG_USB (which is host side support) is not enabled, so also build drivers/usb/ when CONFIG_USB_SUPPORT is enabled so that drivers/usb/common/ is built.
