From: Tao Ren <rentao.bupt@gmail.com> This patch series allows people to customize aspeed-usb-vhub device IDs and strings via device tree. Patch #1 converts the single "usb_gadget_strings" instance to a list of "usb_gadget_strings" so it's more convenient to support miltiple languages. Patch #2 moves LANGID validation code from configfs.c to usbstring.c so it can be used by aspeed-vhub driver. Patch #3 initializes aspeed-vhub strings with default, or from device tree if according device tree properties are defined. Patch #4 overrides aspeed-vhub's device IDs if according properties are defined in device tree. Patch #5 moves fixup-usb1-dev-desc logic from get-descriptor handler to vhub-init time so the descriptor is patched only once. Patch #6 documents new device tree properties in dt-binding document.
