The ASoC core assumes that the PCM component of the ASoC card transparently moves data around and does not impose any restrictions on the memory layout or the transfer speed. It ignores all fields from the snd_pcm_hardware struct for the PCM driver that are related to this. Setting these fields in the PCM driver might suggest otherwise though, so rather not set them.
I suppose that makes sense; the data format is determined by the FIFO in the DAI/controller, not the DMA engine that's pushing the data there (unless DMA can do data conversions, though I think our HW can't?).
