I see. The difficulty with more than one register based device is somewhat orthogonal to the DAIs. The current approach to such systems is to have a driver for one of the devices which provides functions which can be called from the machine drivers - the MAX9877 and TPA6130A2 in mainline are examples. This doesn't scale so well, though it is workable for the time being if the devices aren't too complex. _______________________________________________ Alsa-devel mailing list Alsa-devel@xxxxxxxxxxxxxxxx http://mailman.alsa-project.org/mailman/listinfo/alsa-devel
