help
DMA engines can do asynchronous data transfers without
involving the host CPU. Currently, this framework can be
used to offload memory copies in the network stack and
RAID operations in the MD driver. This menu only presents
DMA Device drivers supported by the configured arch, it may
be empty in some cases.
config DMADEVICES_DEBUG

help
This is an option for use by developers; most people should
say N here. This enables DMA engine core and driver debugging.

bool "DMA Engine verbose debugging"
depends on DMADEVICES_DEBUG != n
help
This is an option for use by developers; most people should
say N here. This enables deeper (more verbose) debugging of
