I tend to disagree since the dts include the armada-xp.dtsi, which already declare

"i2c0: i2c@11000 {
				compatible = "marvell,mv78230-i2c", "marvell,mv64xxx-i2c";
				reg = <0x11000 0x100>;
			};
"

I tested the dts on the device and it does inherits the i2c declaration, did I miss something here ?
