| |
From: Vladimir Oltean <vladimir.oltean@nxp.com>
LS1028A has a functional connection to the eDMA module. Even if the spi-fsl-dspi.c driver is not using DMA for LS1028A now, define the slots in the DMAMUX for connecting the eDMA channels to the 3 DSPI controllers.
Signed-off-by: Vladimir Oltean <vladimir.oltean@nxp.com> --- Changes in v3: None.
Changes in v2: None.
