    Subject[PATCH v3 02/16] dt-bindings: iio: adc: add binding for X-Powers AXP PMICs ADC
    Date
    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:
