Subject: [PATCH 1/2] dt-bindings: dma: fsl-edma: fix ls1028a-edma compatible
Date: Fri, 6 Mar 2020 21:54:02 +0100 [thread overview]
Message-ID: <20200306205403.29881-1-michael@walle.cc> (raw)
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.
Signed-off-by: Michael Walle <michael@walle.cc>
Fixes: d8c1bdb5288d ("dt-bindings: dma: fsl-edma: add new fsl,fsl,ls1028a-edma")
