I'm porting a driver from ARM to PowerPC, and I came across this function:
static int at91_pcm_mmap(struct snd_pcm_substream *substream,
struct vm_area_struct *vma)
{
struct snd_pcm_runtime *runtime = substream->runtime;
return dma_mmap_writecombine(substream->pcm->card->dev, vma,
runtime->dma_area,
runtime->dma_addr,
runtime->dma_bytes);
}
There are no dma_mmap_x() functions in arch/powerpc. Can someone tell me what
the powerpc
equivalent to dma_mmap_writecombine() is?
