Subject: [PATCH v4 3/7] usb: gadget: aspeed: add ast2600 vhub support
Date: Wed, 26 Feb 2020 15:03:42 -0800 [thread overview]
Message-ID: <20200226230346.672-4-rentao.bupt@gmail.com> (raw)
In-Reply-To: <20200226230346.672-1-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.
Signed-off-by: Tao Ren <rentao.bupt@gmail.com>
Reviewed-by: Andrew Jeffery <andrew@aj.id.au>

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