In fact, I saw that there are three other upstream dts files using this driver. In general, I assumed that anything with a DT binding has users, with the exception of the devices inside of a removed SoC and a few PMIC chips that were tightly linked to a removed SoC from the same manufacturer. Thanks a lot for checking the list! Arnd
