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

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

   45       The polarity, whether the interrupt is active on the rising
   46       or the falling edge, is software-configurable in the hardware.
