From 983565dcd368782495f3988e78888289e32f46b3 Mon Sep 17 00:00:00 2001 From: Gregory CLEMENT Date: Tue, 31 Dec 2013 17:07:35 +0100 Subject: i2c: mv64xxx: Document the newly introduced Armada XP A0 compatible 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.
