Patch per se looks good. But can you test if it works to just throw atmel_pcm_dma_hardware away completely and rely on the dmaengine PCM driver getting the capabilities directly from the DMA driver. Since the DMA driver now reports its capabilities I think it should work, and if it does that's the preferred solution.
