+
+Required node properties:
+- compatible: manufacture and chip name,
+ which are listed in the Documentation/hwmon/lm90
+- reg: I2C bus address of the device
+
+Optional properties:
+- 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:
+
+nct1008 {
+ compatible = "onnn,nct1008";
+ reg = <0x4c>;
+ vdd-supply = <&palmas_ldo6_reg>;
+ interrupt-parent = <&gpio>;
