14 On SOCs that have an SSI, specific DMA channels are hard-wired for playback
15 and capture. On the MPC8610, for example, SSI1 must use DMA channel 0 for
16 playback and DMA channel 1 for capture. SSI2 must use DMA channel 2 for
17 playback and DMA channel 3 for capture. The developer can choose which
