How to configure device tree overlay to have spidev1.1?

So far, I have /dev/spidev1.0 and /dev/spidev2.0 in linux, and both of them work well. I hope to switch the /dev/spidev1.0 to /dev/spidev1.1. Is it possible?

It seems that I just need to update the device tree overlay. Please tell me how to confiure device tree overlay to get /dev/spidev1.1

Thanks a lot.
