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.
