|
|
|
|
Required properties:
|
|
|
|
- compatible: should be "ti,lmp91000"
|
|
- reg: the I2C address of the device
|
|
- io-channels: the phandle of the iio provider
|
|
|
|
- ti,external-tia-resistor: if the property ti,tia-gain-ohm is not defined this
|
|
needs to be set to signal that an external resistor value is being used.
|
|
|
|
Optional properties:
|
|
|
|
- ti,tia-gain-ohm: ohm value of the internal resistor for the transimpedance
|
|
amplifier. Must be 2750, 3500, 7000, 14000, 35000, 120000, or 350000 ohms.
|
|
|
|
- ti,rload-ohm: ohm value of the internal resistor load applied to the gas
|
|
sensor. Must be 10, 33, 50, or 100 (default) ohms.
|
|
|
|
Example:
|
|
|
|
lmp91000@48 {
|
|
compatible = "ti,lmp91000";
|
|
reg = <0x48>;
|
|
ti,tia-gain-ohm = <7500>;
|
|
ti,rload = <100>;
|
|
io-channels = <&adc>;
|
|
};
