Rob Herring 6ac02df3ff dt-bindings: virtio,mmio: Allow setting devices 'dma-coherent'
'virtio,mmio' devices are always coherent within a guest. As Arm DTs
are default non-coherent, the 'dma-coherent' property needs to be set on
the virtio device to mark them as such. This aligns with the QEMU 'virt'
machine DTB.
