    iio: dac: add support for stm32 DAC · 4d4b3052

    Add support for STMicroelectronics STM32 DAC. It's a 12-bit, voltage
    output digital-to-analog converter. It has two output channels, each
    with its own converter.
    It supports 8 bits or 12bits left/right aligned data format. Only
    12bits right-aligned is used here. It has built-in noise or
    triangle waveform generator, and supports external triggers for
    conversions.
    Each channel can be used independently, with separate trigger, then
    separate IIO devices are used to handle this. Core driver is intended
    to share common resources such as clock, reset, reference voltage and
    registers.
