- reg: i2c address of the sensor / spi cs line



Optional properties:

- drive-open-drain: the interrupt/data ready line will be configured

  as open drain, which is useful if several sensors share the same

  interrupt line. This is a boolean property.

  If the requested interrupt is configured as IRQ_TYPE_LEVEL_HIGH or

  IRQ_TYPE_EDGE_RISING a pull-down resistor is needed to drive the line

  when it is not active, whereas a pull-up one is needed when interrupt

  line is configured as IRQ_TYPE_LEVEL_LOW or IRQ_TYPE_EDGE_FALLING.

  Refer to pinctrl/pinctrl-bindings.txt for the property description.

- interrupt-parent: should be the phandle for the interrupt controller

- interrupts: interrupt mapping for IRQ. It should be configured with

  flags IRQ_TYPE_LEVEL_HIGH, IRQ_TYPE_EDGE_RISING, IRQ_TYPE_LEVEL_LOW or
