The documentation for ASoC is in: Documentation/sound/alsa/soc which should give you a reasonable structural overview of things. Probably the easiest thing for you to do is to clone the driver for a simple I2C controlled CODEC such as the WM8523 and then replace all the specifics of the register access with those for your CODEC. _______________________________________________ Alsa-devel mailing list Alsa-devel@xxxxxxxxxxxxxxxx http://mailman.alsa-project.org/mailman/listinfo/alsa-devel
