From d6ee805325b1d082fa33be3024163e5f7931ed54 Mon Sep 17 00:00:00 2001 From: Biju Das Date: Wed, 30 Aug 2017 16:17:14 +0100 Subject: [PATCH] ARM: dts: iwg22d-sodimm: Add Ethernet AVB support Define the iWave RainboW-G22D board dependent part of the Ethernet AVB device node. On some older versions of the platform (before R4.0) the phy address may be 1 or 3. The address is fixed to 3 for R4.0 onwards (which will be the first mainstream release), hence using 3 in the dts.
