[PATCH v4 3/7] usb: gadget: aspeed: add ast2600 vhub support

From: <hidden>
Date: 2020-02-26 23:04:11
Also in: linux-aspeed, linux-devicetree, linux-usb, lkml, openbmc
Subsystem: the rest, usb subsystem · Maintainers: Linus Torvalds, Greg Kroah-Hartman

From: Tao Ren <redacted>

Add AST2600 support in aspeed-vhub driver. There are 3 major differences
between AST2500 and AST2600 vhub:
  - AST2600 supports 7 downstream ports while AST2500 supports 5.
  - AST2600 supports 21 generic endpoints while AST2500 supports 15.
  - EP0 data buffer's 8-byte DMA alignment restriction is removed from
    AST2600.

 No Change in v3/v4.
 Changes in v2:
   - removed "ast_vhub_config" related logic.
