    iio: imu: adis16480: Add support for configurable drdy indicator · cede2f89
    stefpopa authored
    The FNCTIO_CTRL register provides configuration control for each I/O pin
    (DIO1, DIO2, DIO3 and DIO4).
    This patch adds the option to configure each DIOx pin as data ready
    indicator with positive or negative polarity by reading the 'interrupts'
    and 'interrupt-names' properties from the devicetree. The
    'interrupt-names' property is optional, if it is not specified, then the
    DIO1 pin is used as default data ready signal.
    Although the factory default assigns DIO2 as data ready signal, in the
    versions previous this patch, DIO1 pin was used. We should leave this
    configuration as is, since some devices might be expecting the interrupt
    on the wrong physical pin.
