Unless it is very recent, I don't the the invensense vendor-prefix is in vendor-prefixes.txt. Please add that to the patch. Otherwise, there is nothing here that isn't covered by the trivial i2c bindings - thus perhaps it should be an entry in bindings/i2c/trivial-devices.txt? Personally I'm not that fond of the trivial file as a single location for the relevant info makes more sense to me. Still thought I'd bring it up as a possibility. Jonathan
