[alsa-devel] [PATCH 1/6] ASoC: dmaengine_pcm: Add dma_name to snd_dmaengine_dai_dma_data

DAI drivers can set the dma_name to the desired one instead of filter_data
when booting with device tree in order to be able to get the correct DMA
channel in DT boot.
When booting with devicetree the platform_get_resource_byname() is not
available for DMA resources.
