29          provides DMA capabilities for a variety of peripheral buses such
30          as I2C, UART, and SPI. By using GPI dmaengine driver, bus drivers
31          can use a standardize interface that is protocol independent to
32          transfer data between DDR and peripheral.

40	  Each DMA device requires one management interface driver
41	  for basic initialization before QCOM_HIDMA channel driver can
42	  start managing the channels. In a virtualized environment,
43	  the guest OS would run QCOM_HIDMA channel driver and the
44	  host would run the QCOM_HIDMA_MGMT management driver.

54	  memcpy interface. The core is not intended for general
55	  purpose slave DMA.
