[PATCH] dt-bindings: i2c: Add armada-38x i2c binding

From: Kalyan Kinthada
Date: Thu Sep 21 2017 - 22:04:49 EST


All armada-38x variants(380, 385, 388) SoCs have an issue
in i2c controller which violates the i2c repeated start timing.

This errata is fixed in the i2c-mv64xxx driver but enabled
only for devices with compatible string "marvell,mv78230-i2c".

This patch introduces a new compatible string
"marvell,armada-38x-i2c" for the i2c controller on armada-38x SoCs
so that the workaound is enabled.
