    description:

      Must be the device tree identifier of the RESET pin. If specified,

    description:

      Configures the device SYNC pin. The following modes are supported

    description:

      This property must be present if the clock mode is scaled-sync through

      clock-names property. In this mode, the input clock can have a range

      of 1Hz to 128HZ which must be scaled to originate an allowable sample

      rate. This property specifies that rate.
