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.
