+ 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.

+ 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.

+ 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.
