AFAICT this patch is fixing the binding for the ArcticSand devices to use the correct value from vendor-prefixes.yaml and has been previously discussed here: https://lkml.org/lkml/2018/9/25/726 Currently this patch series just updates the DT bindings but the implementation also honours the old values (since there is a Chromebook in the wild that uses the current bindings). Hence I'm not clear whether the bindings should document the deprecated options too (e.g. make it easier to find the bindings doc with git grep and friends).
