X-Powers PMICs have several ADC channels that can be used for different purposes, e.g. PMIC internal temperature, battery voltage or AC current. This is the documentation for AXP209, AXP221/223 and AXP813 ADC bindings.

* X-Powers AXP ADC bindings
|
|
|
|
Required properties:
|
|
- compatible: should be one of:
|
|
- "x-powers,axp209-adc",
|
|
- "x-powers,axp221-adc",
|
|
- "x-powers,axp813-adc",
|
|
- #io-channel-cells: should be 1,
|
|
|
|
Example:
|
|
|
|
&axp22x {
|
|
adc {
|
|
compatible = "x-powers,axp221-adc";
|
|
#io-channel-cells = <1>;
|
|
};
|
|
};
|
|
|
