You can of course list an rfkill property inside the device node where it is connected to, but what are you going to to if there is no device node, e.g. the device is enumerated on a bus (e.g. usb, pci, ...)? In such cases it may be better to define a standalone rfkill node similar to the "backlight" device, even if it just contains a gpio or regulator.

This label is used by rfkill (converted to pdata->name in probe
function) and used for displaying.
Maybe label isn't correct name for that purpose.

I did platform data -> DT mapping 1 : 1. Maybe we don't need to export
those to separate
include file and only use raw number instead.

rfkill-regulator in probe check for vrfkill regulator so I've added it
to description as without that rfkill-regulator doesn't make sense.

We can do something like:
gps-device {
compatible = "my-desired-gps";
rfkill = <&gps-rfkill>;
};

rfkill-regulator is linked with regulator so if you have another
device it is probably controlled
with another regulator.

Some time ago was posted rfkill-gpio DT binding conversion and was
using the nearly the same bindings as
we propose and there was no issue with that.

What exactly is an "rfkill" device? How is it used? How does it relate
to other devices in the DT?
To me, this looks like a leak of a Linux abstraction.

What's this for? Why does this need a label in the DT? Surely this can
be implied by the relationship to a particular radio device?

Why isn't this described on the radio revice node? It's a supply to the
radio, not to the rfkill concept.

Why is this not bound to the particular GPS device in some way?
What if I have more than one of any of the types of device this
supports, which device is this expected to control?
Why is it described as a separate device in the device tree at all?
I do not think this binding is the right way to describe this.

I also think this should be renamed to rfkill.h because same defines
could be used for rfkill-gpio driver.
