Several approaches have been tried in the past. Consider adding
these lore links:

"[PATCH 3/4] gpio: dt-bindings: Declare gpio-hog optional for GPIO
subnodes" (2016)
https://lore.kernel.org/linux-devicetree/1456214089-13954-3-git-send-email-mpa@xxxxxxxxxxxxxx/
"[PATCH] gpio: 74x164: add lines-initial-states property" (2018)
https://lore.kernel.org/lkml/20180815201855.29738-1-mail@xxxxxxxxxxxxxxx/";
"[RFC] Initial state for GPIOs" (2019)
https://lore.kernel.org/linux-gpio/bee53b48c96603ae8970d42bc4bff386b876bc51.camel@xxxxxxxxxxxxx/

Just so we don't have to constantly look them up for referral.
