arch/ppc or arch/powerpc?

If the latter, you need to translate the hardware IRQ into a virtual 
IRQ.  The easiest way to do this is to put the DMA node into the device 
tree and use of_irq_to_resource().

Plus, this obviously isn't the exact code you're running, as the 
spelling and capitalization errors would keep it from compiling.
