The tag is gone in this version, presumably meaning that there was a substantial change. I don't normally do this, but I downloaded v12 and v13 and did not find a single change. Why did you drop Rob's Reviewed-by: tag ? Guenter

Why did you drop Rob's Reviewed-by: tag ? Hi Guenter, The fan DT-binding for version 12 is identical to that of version 13. I apologize for forgetting to include the 'Reviewed-by' from Rob when preparing version 13. I will make sure to include it when sending version 14. Thanks
