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

- Enable support for the Qualcomm Technologies HIDMA controller.
- The HIDMA controller supports optimized buffer copies
- (user to kernel, kernel to kernel, etc.). It only supports
- memcpy interface. The core is not intended for general
- purpose slave DMA.
