  st,disable-sensor-hub:
    type: boolean
    description:
      Enable/disable internal i2c controller slave autoprobing at bootstrap.
      Disable sensor-hub is useful if i2c controller clock/data lines are
      connected through a pull-up with other chip lines (e.g. SDO/SA0).

  drive-open-drain:
    type: boolean
    description:
      The interrupt/data ready line will be configured as open drain, which
      is useful if several sensors share the same interrupt line.
