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.

+ 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

- 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
