Date: Fri, 29 Sep 2017 10:36:03 +1300 Message-Id: <20170928213605.22874-1-kalyan.kinthada@alliedtelesis.co.nz> X-Mailer: git-send-email 2.14.1 Sender: linux-i2c-owner@vger.kernel.org Precedence: bulk List-ID: X-Mailing-List: linux-i2c@vger.kernel.org All the Armada 38x(380, 385, 388) have a silicon issue in the I2C controller which violates the I2C repeated start timing (errata FE-8471889). Activate the compatible string "marvell,mv78230-a0-i2c" in the device tree file of Armada-38x to fx this errata (FE-8471889). Updated the Documentation for the compatible string "marvell,mv78230-a0-i2c". Thank You Gregory Clement for suggesting to reuse the "marvell,mv78230-a0-i2c" compatible string on Armada-38x SoCs.
