In linux kernel since version 4.1 (release Date: 2015-06-21)  
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.
