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. config QCOM_GPI_DMA tristate "Qualcomm Technologies Inc GPI DMA support" depends on ARCH_QCOM select DMA_ENGINE select DMA_VIRTUAL_CHANNELS help Enable support for the QCOM GPI DMA controller. This controller provides DMA capabilities for a variety of peripheral buses such as I2C, UART, and SPI. By using GPI dmaengine driver, bus drivers can use a standardize interface that is protocol independent to transfer data between DDR and peripheral. config QCOM_GPI_DMA_DEBUG bool "Qualcomm Technologies Inc GPI debug support" depends on QCOM_GPI_DMA help Enable detailed logging for QCOM GPI driver. Extra logging will be helpful when debugging critical issues. config QCOM_PCI_EDMA tristate "Qualcomm Technologies Inc PCIe eDMA support" select DMA_ENGINE help Enable support for the QCOM PCIe eDMA. This DMA is part of QCOM PCIe controller that provides DMA capabilities for clients. By using PCIe eDMA driver, clients can use a standardize interface that is protocol independent to transfer data between DDR and peripheral. config QCOM_PCI_EDMA_DEBUG bool "Qualcomm Technologies Inc PCIe eDMA debug support" depends on QCOM_PCI_EDMA help Enable detailed logging for QCOM PCIe eDMA driver. Should only be enabled for debugging purpose since excessive logging of all channels information and activity will decrease throughput.
