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.
