Hi all, Im working with Linux 5.10 on my imx8mm.

In the linux I can see pinctrl-maps here:  /sys/kernel/debug/pinctrl/pinctrl-maps

It is according to the Device Tree files,

 

Below there is my investigation picture,
I see that blue, pink and violet marked pins are registered in the pinctrl-maps
(there is wrong green marked group in this picture by mistake).

The question is how to create node (device) in the device tree and add pinctrl pins groups to the Linux.
It works for I2C4 in my case but does not work for os02g10. What can be wrong?
