    6 Required properties:
    7 
    8   - compatible: should be one of the following:
    9                  "ti,lmp91000"
   10                  "ti,lmp91002"
   11   - reg: the I2C address of the device
   12   - io-channels: the phandle of the iio provider
   13 
   14   - ti,external-tia-resistor: if the property ti,tia-gain-ohm is not defined this
   15     needs to be set to signal that an external resistor value is being used.
   16 
   17 Optional properties:
   18 
   19   - ti,tia-gain-ohm: ohm value of the internal resistor for the transimpedance
   20     amplifier. Must be 2750, 3500, 7000, 14000, 35000, 120000, or 350000 ohms.
   21 
   22   - ti,rload-ohm: ohm value of the internal resistor load applied to the gas
   23     sensor. Must be 10, 33, 50, or 100 (default) ohms.
   24 
   25 Example:
   26 
   27 lmp91000@48 {
   28         compatible = "ti,lmp91000";
   29         reg = <0x48>;
   30         ti,tia-gain-ohm = <7500>;
   31         ti,rload = <100>;
   32         io-channels = <&adc>;
   33 };
