Patch #1 includes vhub's usb descriptors in struct "ast_vhub": all usb descriptor changes will go to the per-vhub instance instead of touching the global default descriptors. Patch #2 replaces hardcoded vhub port/endpoint number with device tree properties, so that it's more convenient to add support for ast2600-vhub which provides more downstream ports and endpoints. Patch #3 enables ast2600 support in aspeed-vhub usb gadget driver. Patch #4 adds USB devices and according pin groups in aspeed-g6 dtsi. Patch #5 and #6 add vhub port/endpoint properties into aspeed-g4 and aspeed-g5 dtsi. Patch #7 adds device tree binding document for aspeed usb-vhub driver.
