| 14 | Enable support for the Qualcomm Technologies HIDMA Management. |
| 15 | Each DMA device requires one management interface driver |
| 16 | for basic initialization before QCOM_HIDMA channel driver can |
| 17 | start managing the channels. In a virtualized environment, |
| 18 | the guest OS would run QCOM_HIDMA channel driver and the |
| 19 | host would run the QCOM_HIDMA_MGMT management driver. |

| 26 | The HIDMA controller supports optimized buffer copies |
| 27 | (user to kernel, kernel to kernel, etc.). It only supports |
| 28 | memcpy interface. The core is not intended for general |
| 29 | purpose slave DMA. |
