config DMA_NXP_EDMA
bool "NXP enhanced Direct Memory Access (eDMA) driver"
default y
depends on DT_HAS_NXP_EDMA_ENABLED
help
Enable driver for NXP's eDMA IP.

config DMA_NXP_EDMA_ALIGN
int "Alignment (in bytes) required for the transfers"
default 8
help
Use this to set the alignment (in bytes)
used by entities employing this driver to
adjust the addresses and sizes of the memory
regions involved in the transfer process.
This value needs to match one of the possible
values for SSIZE and DSIZE, otherwise the
driver will return an error upon configuration.

config DMA_NXP_EDMA_ENABLE_HALFMAJOR_IRQ
bool "Set if CPU should be interrupted when CITER = BITER / 2"
default n
help
Enable this configuration if the CPU should be
interrupted when CITER = BITER / 2. Using this,
the CPU will be interrupted when CITER = BITER and
when CITER = BITER / 2.
