    Subject[v2 2/8] dt-bindings: iio: adc: Binding ast2600 adc.
    Date
    This patch add more description about aspeed adc and add two property
    for ast2600:
    - vref: used to configure reference voltage.
    - battery-sensing: used to enable battery sensing mode for last channel.

    + • 10-bits resolution for 16 voltage channels.
    + At ast2400/ast2500 the device has only one engine with 16 voltage channels.
    + At ast2600 the device split into two individual engine and each contains 8 voltage channels.
    + • Channel scanning can be non-continuous.
    + • Programmable ADC clock frequency.
    + • Programmable upper and lower bound for each channels.
    + • Interrupt when larger or less than bounds for each channels.
    + • Support hysteresis for each channels.
    + • Buildin a compensating method.
    + Additional feature at ast2600
    + • Internal or External reference voltage.
    + • Support 2 Internal reference voltage 1.2v or 2.5v.
    + • Integrate dividing circuit for battery sensing.
