description:
  The Yamaha YAS530 magnetometers is a line of 3-axis magnetometers
  first introduced by Yamaha in 2009 with the YAS530. They are successors
  of Yamaha's first magnetometer YAS529. Over the years this magnetometer
  has been miniaturized and appeared in a number of different variants.

    description: The YAS530 sensor has a RSTN pin used to reset
      the logic inside the sensor. This GPIO line should connect
      to that pin and be marked as GPIO_ACTIVE_LOW.

  interrupts:
    maxItems: 1
    description: Interrupt for INT pin for interrupt generation.
      The polarity, whether the interrupt is active on the rising
      or the falling edge, is software-configurable in the hardware.

  vdd-supply:
    description: An optional regulator providing core power supply
      on the VDD pin, typically 1.8 V or 3.0 V.

  iovdd-supply:
    description: An optional regulator providing I/O power supply
      for the I2C interface on the IOVDD pin, typically 1.8 V.

  mount-matrix:
    description: An optional 3x3 mounting rotation matrix.
