1* HTS221 STM humidity + temperature sensor 2 3Required properties: 4- compatible: should be "st,hts221" 5- reg: i2c address of the sensor / spi cs line 6 7Optional 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. 19 20 Refer to interrupt-controller/interrupts.txt for generic interrupt 21 client node bindings. 22 23Example: 24 25hts221@5f { 26 compatible = "st,hts221"; 27 reg = <0x5f>; 28 interrupt-parent = <&gpio0>; 29 interrupts = <0 IRQ_TYPE_EDGE_RISING>; 30}; 31
