This doesn't look appropriate for DT, it looks more like it should be
loaded as firmware since systems might want to support multiple
configurations at runtime based on use casea.  It would also be good to
have code to validate that any supplied coefficeints/firmware don't
overwrite registers managed by the driver, just in case.
