Allow userspace applications to do more parameter setting by providing a more complete stub DMA driver specifying a wildcard set of formats and channels and essentially random values for the DMA parameters. This is required for useful runtime operation of the dummy DMA driver until we are able to figure out how to power up links and do hw_params() from DAPM.
Is this also intended to be used for hostless DAI links e.g.
MODEM <-> MCBSP <-> DSP
It's for any sort of link that doesn't go through a DMA controller the kernel can see - this is the DMA driver that gets stubbed in when the DAI doesn't have a DMA driver. In the case above I guess it depends on if the DMA controller is hidden by the DSP or not.
Ok, that's what I was thinking.
