On the configuration of device tree in ncs2.0

[mingjkl]

My application originally used the ncs version of 1.5.0, and the configuration project used the dts file of nrf5340dk. When I need to change the rts pin of uart0, I just need to add &uart0 { rts-pin = < 0xFF >; }; to the overlay file.
Now I have trouble adapting my project to NCS version 2.1.0. I found that the part of the nrf5340dk dts file about pin configuration has adopted a new format, and the original overlay file I used cannot be compiled normally.
In NCS 2.1.0, how do I change the pin of uart0?

Hello,

you can change the pin configuration using the pin control API. You can read more about it here. The example code shows how to set the RTS pin for uart0.
