Subject[PATCH v3 11/12] arm64: dts: ls1028a: Specify the DMA channels for the DSPI controllers
Date
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.
