|  | 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 |

|  | The HIDMA controller supports optimized buffer copies | 
|  | (user to kernel, kernel to kernel, etc.).  It only supports |
