* LM90 series thermometer.

Required node properties:
- compatible: manufacturer and chip name, one of
		"adi,adm1032"
		"adi,adt7461"
		"adi,adt7461a"
		"gmt,g781"
		"national,lm90"
		"national,lm86"
		"national,lm89"
		"national,lm99"
		"dallas,max6646"
		"dallas,max6647"
		"dallas,max6649"
		"dallas,max6657"
		"dallas,max6658"
		"dallas,max6659"
		"dallas,max6680"
		"dallas,max6681"
		"dallas,max6695"
		"dallas,max6696"
		"onnn,nct1008"
		"winbond,w83l771"
		"nxp,sa56004"
		"ti,tmp451"

- 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>;
}
