properties:
  compatible:
    const: nxp,fxas21002c

  reg:
    maxItems: 1

  vdd-supply:
    description: Regulator that provides power to the sensor

  vddio-supply:
    description: Regulator that provides power to the bus

  reset-gpios:
    maxItems: 1
    description: GPIO connected to reset

  interrupts:
    minItems: 1
    maxItems: 2
    description: Either interrupt may be triggered on rising or falling edges.

  interrupt-names:
    minItems: 1

    items:
      enum:
        - INT1
        - INT2

  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.

  spi-max-frequency:
    maximum: 2000000
