Subject: [PATCH V3 1/5] dt-bindings: virtio: Add binding for virtio devices
Date: Mon, 26 Jul 2021 10:21:41 +0530 [thread overview]
Message-ID: <fced2f2b9dcf3f32f16866d7d104f46171316396.1627273794.git.viresh.kumar@linaro.org> (raw)
In-Reply-To: <cover.1627273794.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 format
"virtio,<DID>", where DID is virtio device ID in hexadecimal format.
Signed-off-by: Viresh Kumar <viresh.kumar@linaro.org>
