Could someone tell me how to mmap a dma buffer allocated with
dma_alloc_coherent? I have found some patches that Takashi Iwai
submitted to create a dma_mmap_coherent function but it doesn't look
like its been accepted upstream, is there a reason why? Is there a
better way for mmaping a dma address? I am trying to get mmaping
working on a mpc5121e i2s audio driver so that I can do alsa audio
mixing.
Thanks,
Gabe
