The documentation is a bit outdated, the GPIO subsystem supports both
-gpio and -gpios, see commit:

dd34c37aa3e8 ("gpio: of: Allow -gpio suffix for property names")

So it makes sense to me to use -gpio instead of -gpios in this case
since is a single GPIO. Also rst is already a descriptive name since
that's how many datasheets name a reset pin. I'm not saying I'm
against this patch, just pointing out since the commit message is a
bit misleading.

Best regards,
Javier
