dt-bindings: virtio: mmio: add optional wakeup-source property
...
Some systems want to set the interrupt of virtio_mmio device
as a wakeup source. On such systems, we'll use the existence
of the "wakeup-source" property as a signal of requirement.

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.

dt-bindings: virtio: Add binding for virtio devices
...
Allow virtio device sub-nodes to be added to the virtio mmio or pci
nodes. The compatible property for virtio device must be of the format
"virtio,device<ID>", where ID is virtio device ID in hexadecimal format.
