-
-- 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>;
