From 09f0b50ae838bd6e2bbf0aa22de9f352122297de Mon Sep 17 00:00:00 2001 From: John Crispin Date: Fri, 22 Apr 2016 11:06:03 +0200 Subject: [PATCH 079/102] net-next: mediatek: add fixed-phy support 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.
