Originally "Platform" component is for "DMA" transfer (But I'm not sure detail. It had been exist when I started to work for ALSA SoC...) But in many SoC, "CPU" component is doing it. Some SoC needs special "Platform" in my understanding.
Right, most systems needed a separate driver for DMA historically - they still do but for a lot of them it's now done less visibly by the dmaengine integration.
