 parent

Hi!

Changelog explains author is not sure if this will break existing
setups:

> This rate change wasn't propagated until now, and it's unclear about cases
> where this shouldn't be propagated. Thus, it's unclear whether this is
> fixing a bug, or extending the current driver behavior. Also, it's unsure
> about whether this may break any existing setups; in the case that it does,
> a device-tree property may be added to disable this flag.

I don't see explanation how this fixes any user bug, so this may not
be good patch for stable?

Best regards,
