From 0e31666dfa043ab71fb1fbbba4feacfe8af3e06b Mon Sep 17 00:00:00 2001 From: Chris Packham Date: Thu, 10 Jan 2019 21:01:00 +1300 Subject: ARM: mvebu: add support for Allied Telesis x530 This is a range of stackable network switches. The SoC is Armada-385 and there are a number of variants with differing network port configurations. The DP variants are intended for a harsher operating environment so they use a different i2c mux and fit industrial-temp parts.
