From 2d2a514c1d61d8cbe00f22f27ff51623d3be89e6 Mon Sep 17 00:00:00 2001 From: Chris Packham Date: Wed, 16 Mar 2022 10:52:07 +1300 Subject: [PATCH] net: mvneta: Add support for 98DX2530 Ethernet port The 98DX2530 SoC is similar to the Armada 3700 except it needs a different MBUS window configuration. Add a new compatible string to identify this device and the required MBUS window configuration.
