It also adds the relevant default configuration on stm32mp15. Not sure why v6.2 is relevant. That changes in connection to usb hubs/companion hubs/peer hubs have been merged some time ago. It would be lovely to see also peer hubs part in u-boot too but nothing wrong with this part. Acked-by: Michal Simek Thanks, Michal
