(it was suggested to deprecate -embedded in favour of -dev, so, added to cc:)

There are also some .dts examples upstream already, e.g., arch/powerpc/boot/dts/kuroboxH[GD].dts. There also have been more patches recently to add further devices to the table and further .dts entries. Notice however, it would be good to move the generic code out of fsl_soc.c, as there seems to be increasing interest in describing i2c buses in .dts.
