But what is this property meant to say, actually? Looking at the DT I guess you want to mark GPIOs as not connected/exposed or such? I don't think this is the intended purpose of this property, it's more for describing ranges of GPIOs not implemented in the GPIO *controller* - say there are 18 pins on PortA, but pins 9-12 are not implemented (no registers) - check Documentation/devicetree/bindings/gpio/gpio.txt. But keep in mind that the Allwinner pinctrl device does not use this kind of per-port binding in the first place, and I wouldn't know of any SoC having non-consecutive pins per port anyway. So I think this is not needed, not in this binding, and not in the DT. Cheers, Andre P.S. Feel free to discuss things in replies to emails - that's why we have those mails. In the past you seemed to always answer very quickly with a new series, even though you seemed to disagree on some things (RTC?) > Signed-off-by: Lukas Schmid <lukas.schmid@xxxxxxxxxx> > --- > .../bindings/pinctrl/allwinner,sun4i-a10-pinctrl.yaml | 5 +++++ > 1 file changed, 5 insertions(+) > > diff --git a/Documentation/devicetree/bindings/pinctrl/allwinner,sun4i-a10-pinctrl.yaml b/Documentation/devicetree/bindings/pinctrl/allwinner,sun4i-a10-pinctrl.yaml > index 450240570314..24b90a5538d6 100644 > --- a/Documentation/devicetree/bindings/pinctrl/allwinner,sun4i-a10-pinctrl.yaml > +++ b/Documentation/devicetree/bindings/pinctrl/allwinner,sun4i-a10-pinctrl.yaml > @@ -83,6 +83,11 @@ properties: > > gpio-controller: true > interrupt-controller: true > + > + gpio-reserved-ranges: > + minItems: 1 > + maxItems: 90 > + > gpio-line-names: true > > input-debounce:
