atmel-pcm-dma is not limited to a buffer size of 64kB like atmel-pcm-pdc. Increase buffer_bytes_max to 512kB to allow for higher bit rates (i.e. 32bps at 192kHz) to work correctly. By default, keep the prealloc at 64kB.
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.
