	  Support for the NVIDIA Tegra20 APB DMA controller driver. The

	  DMA controller is having multiple DMA channel which can be

	  configured for different peripherals like audio, UART, SPI,

	  I2C etc which is in APB bus.

	  This DMA controller transfers data from memory to peripheral fifo

	  or vice versa. It does not support memory to memory data transfer.
