Subject: [PATCH V4 1/5] dt-bindings: virtio: Add binding for virtio devices
Date: Tue, 27 Jul 2021 10:53:48 +0530	[thread overview]
Message-ID: <d8319fd18df7086b12cdcc23193c313893aa071a.1627362340.git.viresh.kumar@linaro.org> (raw)
In-Reply-To: <cover.1627362340.git.viresh.kumar@linaro.org>

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.
