Even if some current systems where the driver is used are using 24 MHz clock, that doesn't mean there wouldn't be systems using another frequency that the driver does not support right now. The driver really should not set the frequency unless it gets it from DT, but I think the preferred means is to use assigned-clock-rates instead, and not to involve the driver with setting the frequency. Otherwise we'll make it impossible to support other frequencies, at least without more or less random defaults. -- Kind regards, Sakari Ailus
