arm64: dts: ls1028a: Specify the DMA channels for the DSPI controllers (dd12fa69) · Commits · 戴 / test

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:
