This set of patches fixes the basic audio support for am335x-evm. It should also be relatively simple to add the necessary nodes to relevant dts files to get BeagleBone + AudioCape and am335x-evmsk working too.
The patch set depends on following patches:
[PATCH v2] ARM: dts: add AM33XX EDMA support https://lkml.org/lkml/2013/8/26/57
[PATCH v11 5/8] ARM: dts: add AM33XX SPI DMA support https://lkml.org/lkml/2013/6/18/55
[PATCH v2] ARM: EDMA: Fix clearing of unused list for DT DMA resources https://lkml.org/lkml/2013/7/22/441
I have tried my best not to break the existing support for older davinci boards, but since I do not have those boards I can not be sure.
Some commit comments refer to a dmaengine based davinci audio implementation which is planned for but nothing has been done yet.
Best regards, Jyri
