This regulator +has an active high enable, but the GPIO specifier for enabling the +regulator incorrectly defines it as active-low. This causes the +following warning to occur on boot ... + + WARNING KERN regulator@10 GPIO handle specifies active low - ignored + +The fixed-regulator binding does not use the active-low flag from the +gpio specifier and purely relies of the presence of the +'enable-active-high' property to determine if it is active high or low +(if this property is omitted). Fix this warning by setting the GPIO +to active-high in the GPIO specifier which aligns with the presense of +the 'enable-active-high' property. + +Fixes: 34993594181d ("arm64: tegra: Enable HDMI on Jetson TX1") +Signed-off-by: Jon Hunter +Signed-off-by: Thierry Reding +Signed-off-by: Greg Kroah-Hartman + +--- + arch/arm64/boot/dts/nvidia/tegra210-p2597.dtsi | 2 +- + 1 file changed, 1 insertion(+), 1 deletion(-) + +--- a/arch/arm64/boot/dts/nvidia/tegra210-p2597.dtsi ++++ b/arch/arm64/boot/dts/nvidia/tegra210-p2597.dtsi +@@ -1583,7 +1583,7 @@ + regulator-name = "VDD_HDMI_5V0"; + regulator-min-microvolt = <5000000>; + regulator-max-microvolt = <5000000>; +- gpio = <&exp1 12 GPIO_ACTIVE_LOW>; ++ gpio = <&exp1 12 GPIO_ACTIVE_HIGH>; + enable-active-high; + vin-supply = <&vdd_5v0_sys>; + }; diff --git a/queue-4.9/series b/queue-4.9/series new file mode 100644 index 00000000000..9e8f029d456 --- /dev/null +++ b/queue-4.9/series @@ -0,0 +1 @@ +arm64-tegra-fix-active-low-warning-for-jetson-tx1-regulator.patch
