The patch series aims at enabling USB Host and Gadget support on AST2600
platforms. I'm targeting openbmc tree mainly for some early feedback and
more widespread testing. I'm planning to upstream the patches after
5.6-rc1.

Patch #1 moves hardcoded vhub attributes (number of downstream ports and
endpoints) to "struct ast_hub_config" which is then attached to "struct
of_device_id". By doing this, it will be easier to enable ast2600 vhub
which supports more ports and endpoints.

Patch #2 enables AST2600 support in aspeed-vhub gadget driver.

Patch #3 adds USB devices and according pin groups in aspeed-g6 dtsi.

Tao Ren (3):
  usb: gadget: aspeed: read vhub config from of_device_id
  usb: gadget: aspeed: add ast2600 vhub support
  ARM: dts: aspeed-g6: add usb functions
