I think it should. For one thing, ASoC requires a pointer to a structure in the codec device driver so that it knows which functions to call to change volume. What if you have multiple i2s/ac97 devices and multiple codecs? You'll need to know which i2s device is connected to which codec. The only way to distinguish that is by having a node for the codec under the i2s node. _______________________________________________ Linuxppc-dev mailing list Linuxppc-dev@ozlabs.org https://ozlabs.org/mailman/listinfo/linuxppc-dev
