Subject: i2c: mv64xxx: Document the newly introduced Armada XP A0 compatible
From: Gregory CLEMENT <gregory.clement@xxxxxxxxxxxxxxxxxx>
commit f8b94beb7e6a374cb0de531b72377c49857b35ca upstream.
The first variants of Armada XP SoCs (A0 stepping) have issues related
to the i2c controller which prevent to use the offload mechanism and
lead to a kernel hang during boot.
The commit introduces a new the compatible string
marvell,mv78230-a0-i2c for the i2c controller.
