I'm trying to understand the intended use of the model property in DT spec v0.4-rc1 §2.3.2. Specifically, can "model" be a property in any node of the devicetree? The spec seems to indicate so, but grepping around the DTS files in Linux, it seems to be primarily used as a property of the root node, as a model name for the entire device. There are a few exceptions in Documentation/devicetree/bindings/, but they are mostly in sound/, so it's not clear to me whether this is the "model" I'm referring to here, especially since that isn't present next to "compatible", "reg", and friends in dt-schema/meta-schemas/core.yaml. Is "model" in the §2.3.2 sense meant to be a property of the root node only, or can it appear anywhere with the meaning defined there? Thanks.
