Hmm. There seems to be a gap here. It'd be much easier to maintain consistency in naming and definitions if V4L2 sub-device nodes were also documented to be V4L2 device nodes, just as any other device nodes exposed by drivers through the V4L2 framework. > > The definition should let it clear that only the devnodes > implemented by the V4L2 main driver are considered as > V4L2 device nodes. Why? I don't think we should make assumptions on which driver exposes a device node; this is not visible to the user space after all. -- Sakari Ailus e-mail: sakari.ai...@iki.fi -- To unsubscribe from this list: send the line "unsubscribe linux-doc" in the body of a message to majord...@vger.kernel.org More majordomo info at http://vger.kernel.org/majordomo-info.html
