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. -Scott
