Does anyone know if this is even possible? I have tried with a simple-audio-card setup using the dmic-codec and omap-dmic as the dai. I have also tried hacking out the twl6040 parts of the twl6040 driver to get a dmic only driver. With both of these methods I managed to get the drivers loaded but could get nothing recorded with an Input/Output error, and then on retry a kernel lockup with regards to enabling/disablig the dmic. Doe anyone have any suggestions; or maybe an idea if this is even possible without large changes? Does the dmic driver with twl6040 even work anymore; I expect it doesn't get a lot of testing... Cheers, Jack.
