From: Jyri Sarha <jsarha at ti.com>

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 

[PATCH v11 5/8] ARM: dts: add AM33XX SPI DMA support

[PATCH v2] ARM: EDMA: Fix clearing of unused list for DT DMA resources

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

Some commit comments refer to a dmaengine based davinci audio
implementation which is planned for but nothing has been done yet.

Best regards,
