-* HTS221 STM humidity + temperature sensor
-
-Required properties:
-- compatible: should be "st,hts221"
-- 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.
-- interrupts: interrupt mapping for IRQ. It should be configured with
- flags IRQ_TYPE_LEVEL_HIGH, IRQ_TYPE_EDGE_RISING, IRQ_TYPE_LEVEL_LOW or
- IRQ_TYPE_EDGE_FALLING.
-
- Refer to interrupt-controller/interrupts.txt for generic interrupt
- client node bindings.
-
-Example:
-
-hts221@5f {
- compatible = "st,hts221";
- reg = <0x5f>;
- interrupt-parent = <&gpio0>;
- interrupts = <0 IRQ_TYPE_EDGE_RISING>;
-};
