Enable support for the Qualcomm Technologies HIDMA Management.
|
|
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.
