+
+- reg: I2C bus address of the device
+
+- vcc-supply: vcc regulator for the supply voltage.
+
+Optional properties:
+- interrupts: Contains a single interrupt specifier which describes the
+ LM90 "-ALERT" pin output.
+ See interrupt-controller/interrupts.txt for the format.
+
+Example LM90 node:
+
+temp-sensor {
+ compatible = "onnn,nct1008";
+ reg = <0x4c>;
+ vcc-supply = <&palmas_ldo6_reg>;
+ interrupt-parent = <&gpio>;
+ interrupts = <TEGRA_GPIO(O, 4) IRQ_TYPE_LEVEL_LOW>;
