Overall honestly I think too much responsibility of DT bindings
(and now also ACPI!) is pushed to the subsystem maintainers,
we are Linux GPIO experts, not really hardware description experts.

We do a best effort but the current practice of letting the subsystem
maintainers have the final word on all device tree bindings is
not optimal, I would like to have a DT/OF persons Reviewed-by tag
on any substantially new binding that is not just a copy of what
every other GPIO driver is doing.

Yours,
Linus Walleij
