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
mandatory in any way at all.

Per recent discussions, all the supported compatible values should be
spelled out here, which I assume are:

brcm,kona-gpio
brcm,bcm11130
brcm,bcm11140
brcm,bcm11351
brcm,bcm28145
brcm,bcm28155

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,
