[PATCH V4 5/5] virtio: Bind virtio device to device-tree node

Bind the virtio devices with their of_node. This will help users of the virtio devices to mention their dependencies on the device in the DT itself. Like GPIO pin users can use the phandle of the device node, or the node may contain more subnodes to add i2c or spi eeproms and other users.

[PATCH V4 1/5] 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", where ID is virtio device ID in hexadecimal format. Signed-off-by: Viresh Kumar --- .../devicetree/bindings/virtio/mmio.yaml | 3 +-

[PATCH V4 0/5] virtio: Add virtio-device bindings

Hi, Currently the DT only provides support for following node types for virtio-mmio nodes: virtio_mmio@a00 { dma-coherent; interrupts = <0x00 0x10 0x01>; reg = <0x00 0xa00 0x00 0x200>; compatible = "virtio,mmio";
