From 391df3782914b7f84a78d415f21069a580335646 Mon Sep 17 00:00:00 2001 From: Pawel Dembicki Date: Mon, 29 Oct 2018 20:31:25 +0000 Subject: ramips: mt7620: add EPHY base mdio address changing possibility MIME-Version: 1.0 Content-Type: text/plain; charset=UTF-8 Content-Transfer-Encoding: 8bit In some boards is requred to change the ephy mdio base address. This patch add of property "mediatek,ephy-base-address" in gsw part, which allows to change ephy base address.
