Re: [PATCH 2/2] arm64: dts: ls1028a: add "fsl,vf610-edma" compatible

Hi all,

Am 2020-03-06 21:54, schrieb Michael Walle:
The bootloader does the IOMMU fixup and dynamically adds the "iommus"
property to devices according to its compatible string. In case of the
eDMA controller this property is missing. Add it. After that the IOMMU
will work with the eDMA core.

Is it possible to have this merged, so it gets into the merge window
for 5.7? As I explained in this thread [1], without this compatible
all boards with enabled IOMMU (and who have either sound, lpuart or
i2c enabled), doesn't work.
