28- reg: I2C bus address of the device
29
30- vcc-supply: vcc regulator for the supply voltage.
31
32Optional properties:
33- interrupts: Contains a single interrupt specifier which describes the
34              LM90 "-ALERT" pin output.
35              See interrupt-controller/interrupts.txt for the format.
36
37- #thermal-sensor-cells: should be set to 1. See thermal/thermal-sensor.yaml
38	      for details. See <include/dt-bindings/thermal/lm90.h> for the
39	      definition of the local, remote and 2nd remote sensor index
40	      constants.

46	reg = <0x4c>;
47	vcc-supply = <&palmas_ldo6_reg>;
48	interrupt-parent = <&gpio>;
49	interrupts = <TEGRA_GPIO(O, 4) IRQ_TYPE_LEVEL_LOW>;
50	#thermal-sensor-cells = <1>;
