Thanks Chris Blake, >First off, thank you very much for this patch and your work on the ipq40xx >platform. I have been doing more testing, and it seems that some of the pins >in pinctl are not defined to the correct function. >This is what I am currently seeing on the board:

I was also able to clear up the >errors by fixing the groups for each GPIO in my DTS with the help of >Christian. Example of this is at https://pastebin.com/rQDY3z9c. >Is this something specific with my board, or some other variation with your >patch? I am new to this arch so please excuse me if any of this is noobish. :) Pinctrl driver has proper definitions & values for respective GPIO's in the patch and I did not observe such issues in IPQ4019 DK01, DK04 and other variants of Dakota boards, they work fine as expected.
