   1 * HTS221 STM humidity + temperature sensor
   2
   3 Required properties:
   4 - compatible: should be "st,hts221"
   5 - reg: i2c address of the sensor / spi cs line
   6
   7 Optional properties:
   8 - drive-open-drain: the interrupt/data ready line will be configured
   9   as open drain, which is useful if several sensors share the same
  10   interrupt line. This is a boolean property.
  11   If the requested interrupt is configured as IRQ_TYPE_LEVEL_HIGH or
  12   IRQ_TYPE_EDGE_RISING a pull-down resistor is needed to drive the line
  13   when it is not active, whereas a pull-up one is needed when interrupt
  14   line is configured as IRQ_TYPE_LEVEL_LOW or IRQ_TYPE_EDGE_FALLING.
  15   Refer to pinctrl/pinctrl-bindings.txt for the property description.
  16 - interrupts: interrupt mapping for IRQ. It should be configured with
  17   flags IRQ_TYPE_LEVEL_HIGH, IRQ_TYPE_EDGE_RISING, IRQ_TYPE_LEVEL_LOW or
  18   IRQ_TYPE_EDGE_FALLING.

  20   Refer to interrupt-controller/interrupts.txt for generic interrupt
  21   client node bindings.

  23 Example:

  25 hts221@5f {
  26         compatible = "st,hts221";
  27         reg = <0x5f>;
  28         interrupt-parent = <&gpio0>;
  29         interrupts = <0 IRQ_TYPE_EDGE_RISING>;
  30 };
