On PowerPC the device tree is used to dynamically load the correct codec module. How am I supposed to get this dynamically loaded module registered? The WM8580 codec registers itself.
Modifying the WM9712 codec to register itself on device load works for me. If I don't do this how am I supposed to dynamically find the DAI pointer so that I can call snd_soc_register_dais()?
