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>; } |
