Subject: [PATCH AUTOSEL 5.6 066/606] dt-bindings: dma: fsl-edma: fix ls1028a-edma compatible

From: Michael Walle <michael@...le.cc>

commit d94a05f87327143f94f67dd256932163ac2bcd65 upstream.

The bootloader will fix up the IOMMU entries only on nodes with the
compatible "fsl,vf610-edma". Thus make this compatible string mandatory
for the ls1028a-edma.

While at it, fix the "fsl,fsl," typo.
