3.13-stable review patch. If anyone has any objections, please let me know. ------------------ 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.
