+* LM90 series thermometer.
+Required node properties:
+- compatible: manufacture and chip name,
+ which are listed in the Documentation/hwmon/lm90
+- reg: I2C bus address of the device
+- vdd-supply: vdd regulator for the supply voltage. If this is not set,
+ assuming vdd is always powered.
+- interrupts: lm90 can support interrupt mode, you can set interrupt here.
+Example lm90 node:
+ compatible = "onnn,nct1008";
+ reg = <0x4c>;
+ vdd-supply = <&palmas_ldo6_reg>;
+ interrupt-parent = <&gpio>;
+ interrupts = <TEGRA_GPIO(O, 4) IRQ_TYPE_LEVEL_LOW>;
