Optional properties:

- st,drdy-int-pin: the pin on the package that will be used to signal

  "data ready" (valid values: 1 or 2).

- 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.

  (This binding is taken from pinctrl/pinctrl-bindings.txt)

  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.

- 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
