config QCOM_BAM_DMA tristate "QCOM BAM DMA support" depends on ARCH_QCOM || (COMPILE_TEST && OF && ARM) select DMA_ENGINE select DMA_VIRTUAL_CHANNELS ---help--- Enable support for the QCOM BAM DMA controller. This controller provides DMA capabilities for a variety of on-chip devices. config QCOM_HIDMA_MGMT tristate "Qualcomm Technologies HIDMA Management support" select DMA_ENGINE help 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. config QCOM_HIDMA tristate "Qualcomm Technologies HIDMA Channel support" select DMA_ENGINE help 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.
