Hi Lars
The reason why I'm tring to support DPCM on simple-card is "sampling rate convert". My rcar_sound can convert sampling rate, and I tried to add this feature as rcar_sound property. But, Mark rejected and requests me to use DPCM for it, since it can be common featrue. Current existing simple-card can't use it, and I'm tring. But, am I misunderstanding ?
Is the sample rate converter a extra module, or is the sample rate converter just a feature of the I2S core?
Does this "I2S core" = CPU ? Then, it is CPU's feature. The image is like this
48kHz ---> 48kHz 44.1kHz ---> [CPU] ---> [codec] 96kHz --->
