From: Tao Ren <rentao.bupt@xxxxxxxxx> The patch series aims at enabling USB Host and Gadget support on AST2600 platforms. Patch #1 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 #2 and #3 add vhub port/endpoint properties into aspeed-g4 and aspeed-g5 dtsi. Patch #4 enables ast2600 support in aspeed-vhub usb gadget driver. Patch #5 adds USB devices and according pin groups in aspeed-g6 dtsi. The patch series is sanity tested on AST2520 (Yamp) BMC and AST2600-A0 eval board: - AST2520: created 5 gadget devices with 15 endpoints, and all of them can be enumerated from usb-host side. - AST2600: created 7 gadget devices with 20 endpoints, and all of them can be enumerated from usb-host side.
