    dmaengine: add Qualcomm Technologies HIDMA management driver · 7f8f209f
    Sinan Kaya authored
    The Qualcomm Technologies HIDMA device has been designed to support
    virtualization technology. The driver has been divided into two to follow
    the hardware design.
    
    1. HIDMA Management driver
    2. HIDMA Channel driver
    
    Each HIDMA HW consists of multiple channels. These channels share some set
    of common parameters. These parameters are initialized by the management
    driver during power up. Same management driver is used for monitoring the
    execution of the channels. Management driver can change the performance
    behavior dynamically such as bandwidth allocation and prioritization.
    
    The management driver is executed in host context and is the main
    management entity for all channels provided by the device.
