Subject: [PATCH v2 4/5] usb: gadget: aspeed: add ast2600 vhub support
Date: Wed, 12 Feb 2020 13:57:16 -0800	[thread overview]
Message-ID: <20200212215717.9474-5-rentao.bupt@gmail.com> (raw)
In-Reply-To: <20200212215717.9474-1-rentao.bupt@gmail.com>

From: Tao Ren <rentao.bupt@gmail.com>

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.

 Changes in v2:
   - removed "ast_vhub_config" related logic.
