Subject: [PATCH V4 3/4] net-next: mediatek: add fixed-phy support
Date: Fri,  3 Jun 2016 10:17:08 +0200	[thread overview]
Message-ID: <1464941829-38712-4-git-send-email-john@phrozen.org> (raw)
In-Reply-To: <1464941829-38712-1-git-send-email-john@phrozen.org>

The MT7623 SoC has a builtin gigabit switch. If we want to use it, GMAC1
needs to be configured using a fixed link speed and flow control settings.
The easiest way to do this is to used the fixed-phy driver, allowing us to
reuse the existing mdio polling code to setup the MAC.
