	  Support for the Loongson2 APB DMA controller driver. The
	  DMA controller is having single DMA channel which can be
	  configured for different peripherals like audio, nand, sdio
	  etc which is in APB bus.

	  This DMA controller transfers data from memory to peripheral fifo.
	  It does not support memory to memory data transfer.

	  Support for the Loongson Chain Multi-Channel DMA controller driver.
	  It is discovered on the Loongson-2K chip (Loongson-2K0300/Loongson-2K3000),
	  which has 4/8 channels internally, enabling bidirectional data transfer
	  between devices and memory.
