I am wondering how you think that > SystemReady certification would apply to a whole binding (I can see it > being a per-compatible thing, but that would be a mess I am sure). There's a lot of pieces, but I'll stick to the DT aspects (which is SystemReady IR band). Certification applies to a specific firmware build (which includes the DTB) on a specific board. The testing requirements at the moment (for 2.x) are every binding (compatible) must have a schema, but warnings are allowed. So a "stable" tag would apply to a DTS as a whole. That of course implies that everything within the DTS is stable too. One wrinkle is that SR has no direct requirement that the DTB come from anything upstream. Indirectly, the schemas must exist and be upstream (or acked on the lists) and various distro kernels have to actually boot. For that reason, if we had some tag, it would have to be distinct from SR.
