The gpio-ranges property is part of the gpiolib subsystem. As a result, the binding text is available in section "2.1 gpio- and pin-controller interaction" of Documentation/devicetree/bindings/gpio/gpio.txt For more information please see the patch titled: "pinctrl: msm: fix gpio-hog related boot issues" from this series. Reported-by: Sven Eckelmann <sven.eckelmann@openmesh.com> Tested-by: Sven Eckelmann <sven.eckelmann@openmesh.com> [ipq4019] Reviewed-by: Bjorn Andersson <bjorn.andersson@linaro.org> Signed-off-by: Christian Lamparter <chunkeey@gmail.com> Reviewed-by: Linus Walleij <linus.walleij@linaro.org> --- To help with git bisect, the DT update patch has been intentionally placed after the "pinctrl: msm: fix gpio-hog related boot issues". Otherwise - if the order was reveresed - and bisect decides to split between these two patches, the gpiochip_add_pin_ranges() function will be executed twice with the same parameters for the same pinctrl. --- arch/arm/boot/dts/qcom-apq8064.dtsi | 1 + arch/arm/boot/dts/qcom-apq8084.dtsi | 1 + arch/arm/boot/dts/qcom-ipq4019.dtsi | 1 + arch/arm/boot/dts/qcom-ipq8064.dtsi | 1 + arch/arm/boot/dts/qcom-mdm9615.dtsi | 1 + arch/arm/boot/dts/qcom-msm8660.dtsi | 1 + arch/arm/boot/dts/qcom-msm8960.dtsi | 1 + arch/arm/boot/dts/qcom-msm8974.dtsi | 1 + arch/arm64/boot/dts/qcom/ipq8074.dtsi | 3 ++- arch/arm64/boot/dts/qcom/msm8916.dtsi | 1 + arch/arm64/boot/dts/qcom/msm8992.dtsi | 1 + arch/arm64/boot/dts/qcom/msm8994.dtsi | 1 + arch/arm64/boot/dts/qcom/msm8996.dtsi | 1 + 13 files changed, 14 insertions(+), 1 deletion(-) --- a/arch/arm/boot/dts/qcom-ipq8064.dtsi +++ b/arch/arm/boot/dts/qcom-ipq8064.dtsi @@ -671,6 +671,7 @@ reg = <0x800000 0x4000>; gpio-controller; + gpio-ranges = <&qcom_pinmux 0 0 69>; #gpio-cells = <2>; interrupt-controller; #interrupt-cells = <2>;
