Use assigned-clock-rates to specify the clock rate. Also mark
clock-frequency property as deprecated.

I would phrase it the other way around, this patch mainly deprecates clock-
frequency, and as a side effect recommends usage of assigned-clock-rates.

"Deprecate usage of the clock-frequency propertly. The preferred method
to set clock rates is to use assigned-clock-rates."

Agreed will do that.

I would drop this completely. Drivers need to ensure backward compatibility,
but DT bindings should only document the latest version, the history is
available in git.

Sure will drop it.

While at it, can I enlist you to convert these bindings to yaml ? :-)

Sure will do the honours , will make sure yaml patch is ontop of this patch too.

Shall I enlist you as the maintainer  in the json-schema ?
dt_binding_check says  'maintainers' is a required property.

Do you want to be the new maintainer ? :-) Sakari is maintaining sensor
drivers (in his spare time though) so maybe he could be listed in the DT
bindings too if he wants. Otherwise, I could do it.

Thank you :-)
