Enable support for the Qualcomm Application Data Mover (ADM) DMA
controller, as present on MSM8x60, APQ8064, and IPQ8064 devices.
This controller provides DMA capabilities for both general purpose
and on-chip peripheral devices.

Enable support for the QCOM BAM DMA controller. This controller
provides DMA capabilities for a variety of on-chip devices.

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.

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

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.
