The line #define DMA_BASE IO_ADDRESS(DMA_BASE_ADDR) in it is no longer valid, right? So, we have to either remove it, or fix it, if we think, that other drivers might start using it. And even if we decide to remove it from the header and implement here, wouldn't it be better to choose a name, not beginning with "__"? Something like MX1_DMA_REG, perhaps? Or maybe even we shall remap those registers?
