| Subject: dt-bindings: dma: fsl-edma: fix ls1028a-edma compatible |
| |
| From: Michael Walle <michael@walle.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. |
