[PATCH v2 0/5] aspeed-g6: enable usb support

[rentao . bupt]

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.
