This should be before the PINCTRL section in this file. I believe after
the uart node.

I have not understood your concern, any specific reason as why
remoteproc_wpss node has to be before PINCTRL section?
There is no problem in moving, just wanted to understand the reason.
Thanks,

It's a style that this file is following. The end of the file is for
pinctrl configurations. Before that section is where soc nodes are
modified. There are different sections of the file with comments
delineating them.
Furthermore, adding things to the end of the file is a recipe for
conflicts when applying patches as a maintainer. This is another reason
why we sort the nodes. I suspect having different sections helps here so
that we don't sort everything alphabetically and have pinctrl settings
scattered throughout the file.

Thanks for the explanation, I'll send out a revised patch.
