It looks like most of these are not used. Please remove them.

You should be able to put all that into DT. Take a look at

arch/arm/boot/dts/kirkwood-goflexnet.dts for example.

You can also do this in DT as well. kirkwood-ts219.dtsi has

                i2c at 11000 {
                        status = "okay";
                        clock-frequency = <400000>;

                        s35390a: s35390a at 30 {
                                compatible = "s35390a";
                                reg = <0x30>;
                        };
