Hi,
I just noticed in mainline kernel (pre 3.11-rc1) that OMAP4 audio is not probing anymore. This is because OMAP4 also moved to DT only mode (3.10 DT boot was fine). The issue underneath is that we can not use platform_get_resource_byname() for DMA resources when booted with devicetree.
In case of DT boot we can use the DMA name to request the channel.
Due to technical issues OMAP can not be moved to generic dmaengine pcm as other SoCs did.
Mark: can you queue this series for 3.11? Thank you.
