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.
