SND_ATMEL_SOC_CLASSD selects SND_ATMEL_SOC_DMA but the driver itself handles its own DMA operations and doesn't need anything from atmel-pcm-dma.c or atmel_ssc_dai.c.
Replace SND_ATMEL_SOC_DMA by SND_SOC_GENERIC_DMAENGINE_PCM which is the only one actually required.
This may end up in a configuration leading to a link error:
sound/soc/atmel/atmel_ssc_dai.o: In function `atmel_ssc_set_audio': atmel_ssc_dai.c:(.text+0x79c): undefined reference to `atmel_pcm_dma_platform_register' atmel_ssc_dai.c:(.text+0x79c): relocation truncated to fit: R_AARCH64_CALL26 against undefined symbol `atmel_pcm_dma_platform_register' sound/soc/atmel/atmel_ssc_dai.o: In function `atmel_ssc_put_audio': atmel_ssc_dai.c:(.text+0xf24): undefined reference to `atmel_pcm_dma_platform_unregister' atmel_ssc_dai.c:(.text+0xf24): relocation truncated to fit: R_AARCH64_CALL26 against undefined symbol `atmel_pcm_dma_platform_unregister'
Tested on sama5d2 xplained with the following configuration where nothing selects SND_ATMEL_SOC_DMA:
CONFIG_SND_ATMEL_SOC=y CONFIG_SND_ATMEL_SOC_CLASSD=y
