Date: Thu, 28 Sep 2017 17:04:05 +1300 Message-Id: <20170928040407.8933-1-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" by removing the "notes" because this is applicable for a number of SoCs such as early revisions of Armada XP and the Armada 38x variants. Thank You Gregory Clement for suggesting to reuse the "marvell,mv78230-a0-i2c" compatible string on Armada-38x SoCs. ------ Kalyan Kinthada (2): ARM: dts: Fix I2C repeated start issue on Armada-38x dt-bindings: i2c: Update documentation for "mv78230-a0-i2c" Documentation/devicetree/bindings/i2c/i2c-mv64xxx.txt | 4 ---- arch/arm/boot/dts/armada-38x.dtsi | 4 ++-- 2 files changed, 2 insertions(+), 6 deletions(-)
