    DMM001 is a compact version of the digital multimeter which internal ADC resolution is 24 bit.

    compatible = ["GQQ-DMM001003-000"]

    It can be used as
    high performance DMM to measure DC voltage and small signal DC current. In this class, adc channel 0 is current
    channel, adc channel 1 is voltage channel. DMM001 support signal measurement and continuous measurement. Note that
    if range_ctrl0 and range_ctrl1 not given, internal submodule GPIO device of MIX_DAQT1 will be used to control range.
    Note that calibration default is enabled. This class is legacy driver for normal boot.

    Args:
        i2c:             instance(I2C)/None, which is used to control nct75 and cat24c32. If not given,
                                            emulator will be created.
        ad7175:          instance(ADC)/None, Class instance of AD7175, if not using this parameter, will create emulator
        range_sel:       instance(GPIO),       This can be Pin or xilinx gpio, used to control range.
        meter_sel:       instance(GPIO),       This can be Pin or xilinx gpio, used to control measure channel

    Wolverine is a compact version of the digital multimeter which internal ADC resolution is 24 bit.

    It can be used as
    high performance DMM to measure DC voltage and small signal DC current. In this class, adc channel 0 is current
    channel, adc channel 1 is voltage channel. DMM001 support signal measurement and continuous measurement. Note that
    if range_ctrl0 and range_ctrl1 not given, internal submodule GPIO device of MIX_DAQT1 will be used to control range.
    Note that calibration default is enabled. This class is legacy driver for normal boot.

    The AD9628 is a monolithic, dual-channel, 1.8V supply, 12-bit, 125MSPS/105MSPS analog-to-digital converter (ADC).
    It features a high performance sample-and-hold circuit and onchip voltage reference.
    The digital output data is presented in offset binary, Gray code, or twos complement format.
    A data output clock (DCO) is provided for each ADC channel to ensure proper latch timing with receiving logic.
    1.8V CMOS or LVDS output logic levels are supported. Output data can also be multiplexed onto a single output bus.
