Subject[PATCH v2 0/6] usb: gadget: aspeed: allow to customize vhub device
From: Tao Ren <>

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

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.

Tao Ren (6):
