* 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>; };
