mpc5200 and dma_ops

Inside the ASoC code there a dma_alloc_coherent() call. This call is
failing because dma_ops is null.
--kernel BUG at /home/jonsmirl/fs/arch/powerpc/include/asm/dma-mapping.h:237!
The device is soc-audio which is a platform_device.

How do I get dma_ops filled in for a mpc5200 platform device?
