I wasn't aware that this was actually still specified. I had hoped we were getting rid of mmu-masters before anyone actually started using it, but now I see it in ns2.dtsi and fsl-ls2080a.dtsi. Does anyone know what happened to the plan to use the iommu DT binding for the ARM SMMU instead? Do we now have to support both ways indefinitely?
