* LM90 series thermometer.



Required node properties:

		"adi,adm1032"

- 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.



- #thermal-sensor-cells: should be set to 1. See thermal/thermal-sensor.yaml

	      for details. See <include/dt-bindings/thermal/lm90.h> for the

	      definition of the local, remote and 2nd remote sensor index

	      constants.



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>;

	#thermal-sensor-cells = <1>;
