Maybe you consider changing the subject of the bindings from "misc"
to "hwmon" as not being a major change, but it made me aware that you
are trying to sneak bindings which in my opinion don't belong there
into the hwmon bindings directory. This is not a hardware monitoring
device, it doesn't have anything to do with hardware monitoring, and the
bindings do not belong into bindings/hwmon/.

Maybe you can convince the devicetree maintainers to accept the bindings
into the suggested location, but that will be over my objection.
