If anyone has any objections, please let me know. ------------------ From: Gregory CLEMENT 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.
