         };

this is my dts file section

2

Most likely it is due to GPIO configuration.
Cany you show that?

3

what file define it ?

4

The same DTS,there should be pinctrl group

5

i'm not find this define in dts file

6

This is not gonna work this way.
Can you post whole source?

And why are you using Device tree for ar71xx when it is not fully working and was removed recently completely.

7

i'm use qcawifi driver,this based qca file modify.

8

Well,without source nobody can help you

oh oh oh well ???
