Subject: [U-Boot] [PATCH 09/21] net/phy: add VSC8574 support
Date: Fri, 22 Mar 2013 10:24:00 -0700 [thread overview]
Message-ID: <1363973052-25918-7-git-send-email-yorksun@freescale.com> (raw)
In-Reply-To: <1363973052-25918-1-git-send-email-yorksun@freescale.com>
From: Shaohui Xie <Shaohui.Xie@freescale.com>
The VSC8574 is a quad-port Gigabit Ethernet transceiver with four SerDes
interfaces for quad-port dual media capability. This driver supports SGMII
and QSGMII MAC mode. For now SGMII mode is tested.
