    Subject[PATCH v3 1/2] dt-bindings: iio: adc: Add rtq6056 adc support
    Date
    From: ChiYuan Huang <cy_huang@richtek.com>

    Add the documentation for Richtek rtq6056.

    Signed-off-by: ChiYuan Huang <cy_huang@richtek.com>

    Since v3
    - change the node name to be generic 'adc' in binding example.

    Since v2
    - Change the resistor property name to be generic 'shunt-resistor-micro-ohms'.

    +title: RTQ6056 Bi-Directional Current and Power Monitor with 16-bit ADC

    +description: |
    + The RTQ6056 is a high accuracy current-sense monitor with I2C and SMBus
    + interface, and the device provides full information for system by reading
    + out the loading current and power.
    +
    + The device monitors both of the drops across sense resistor and the BUS
    + voltage, converts into the current in amperes, and power in watts through
    + internal analog-to-digital converter ADC. The programmable calibration,
    + adjustable conversion time, and averaging function are also built in for
    + more design flexibility.
    +
    + Datasheet is available at
    + https://www.richtek.com/assets/product_file/RTQ6056/DSQ6056-00.pdf
