The last cell of 'gpio-ranges' should be number of GPIO pins, and in case of qcom platform it should match msm_pinctrl_soc_data.ngpio rather than msm_pinctrl_soc_data.ngpio - 1. This fixes the problem that when the last GPIO pin in the range is configured with the following call sequence, it always fails with -EPROBE_DEFER. pinctrl_gpio_set_config() pinctrl_get_device_gpio_range() pinctrl_match_gpio_range() Fixes: b7e8f433a673 ("arm64: dts: qcom: Add basic devicetree support for SM8350 SoC") Cc: Vinod Koul <vkoul@xxxxxxxxxx> Signed-off-by: Shawn Guo <shawn.guo@xxxxxxxxxx> --- arch/arm64/boot/dts/qcom/sm8350.dtsi | 2 +- 1 file changed, 1 insertion(+), 1 deletion(-) diff --git a/arch/arm64/boot/dts/qcom/sm8350.dtsi b/arch/arm64/boot/dts/qcom/sm8350.dtsi index 5ef460458f5c..fab211298c35 100644 --- a/arch/arm64/boot/dts/qcom/sm8350.dtsi +++ b/arch/arm64/boot/dts/qcom/sm8350.dtsi @@ -382,7 +382,7 @@ #gpio-cells = <2>; interrupt-controller; #interrupt-cells = <2>; - gpio-ranges = <&tlmm 0 0 203>; + gpio-ranges = <&tlmm 0 0 204>; qup_uart3_default_state: qup-uart3-default-state { rx { -- 2.17.1
