Agreed. Please don't merge this without their approval and hopefully
testing.

I did demote this patch I've been dragging around since 2021 to RFC
status because I'm more interested in making sure it will fit in with
the work on hardware-offloaded network activity LED work that's being
done. I took Andrew's response to the cover letter as an suggestion to
hold off for a little while longer. I can be patient.

Also, this RFC was two-fold. I don't want to duplicate efforts, and I
know this pinctrl driver was written with this functionality in mind. If
someone out there has a hankering to get those LEDs blinking and they
don't want to wait around for me, feel free to use this as a starting
point. I might not get around to the whole netdev trigger thing for
quite some time!
