The simple way to avoid the discussion re: the name of the file might
have been to name it exactly matching the compatible value it documents,
i.e. brcm,kona-gpio.txt. That's what I personally prefer, but it's not

Per recent discussions, all the supported compatible values should be
spelled out here, which I assume are:
Documenting all of them allows drivers to implement quirks/workarounds
based on individual SoCs if ever needed.
Aside from that, the binding seems reasonable, so the binding,
