In my opinion this binding exposes way to much of the ASoC internal data structures. E.g. CODECs are referenced by phandle, but the DAI of the CODEC is reference by a string. This string is completely ASoC internal. The binding also assumes that a CPU controller may have one DAI at most. In my opinion this binding ought to use the upcoming of_xlate stuff for ASoC components. - Lars -- To unsubscribe from this list: send the line "unsubscribe devicetree" in the body of a message to majordomo@xxxxxxxxxxxxxxx More majordomo info at http://vger.kernel.org/majordomo-info.html
