1*4882a593Smuzhiyun* HTS221 STM humidity + temperature sensor 2*4882a593Smuzhiyun 3*4882a593SmuzhiyunRequired properties: 4*4882a593Smuzhiyun- compatible: should be "st,hts221" 5*4882a593Smuzhiyun- reg: i2c address of the sensor / spi cs line 6*4882a593Smuzhiyun 7*4882a593SmuzhiyunOptional properties: 8*4882a593Smuzhiyun- drive-open-drain: the interrupt/data ready line will be configured 9*4882a593Smuzhiyun as open drain, which is useful if several sensors share the same 10*4882a593Smuzhiyun interrupt line. This is a boolean property. 11*4882a593Smuzhiyun If the requested interrupt is configured as IRQ_TYPE_LEVEL_HIGH or 12*4882a593Smuzhiyun IRQ_TYPE_EDGE_RISING a pull-down resistor is needed to drive the line 13*4882a593Smuzhiyun when it is not active, whereas a pull-up one is needed when interrupt 14*4882a593Smuzhiyun line is configured as IRQ_TYPE_LEVEL_LOW or IRQ_TYPE_EDGE_FALLING. 15*4882a593Smuzhiyun Refer to pinctrl/pinctrl-bindings.txt for the property description. 16*4882a593Smuzhiyun- interrupts: interrupt mapping for IRQ. It should be configured with 17*4882a593Smuzhiyun flags IRQ_TYPE_LEVEL_HIGH, IRQ_TYPE_EDGE_RISING, IRQ_TYPE_LEVEL_LOW or 18*4882a593Smuzhiyun IRQ_TYPE_EDGE_FALLING. 19*4882a593Smuzhiyun 20*4882a593Smuzhiyun Refer to interrupt-controller/interrupts.txt for generic interrupt 21*4882a593Smuzhiyun client node bindings. 22*4882a593Smuzhiyun 23*4882a593SmuzhiyunExample: 24*4882a593Smuzhiyun 25*4882a593Smuzhiyunhts221@5f { 26*4882a593Smuzhiyun compatible = "st,hts221"; 27*4882a593Smuzhiyun reg = <0x5f>; 28*4882a593Smuzhiyun interrupt-parent = <&gpio0>; 29*4882a593Smuzhiyun interrupts = <0 IRQ_TYPE_EDGE_RISING>; 30*4882a593Smuzhiyun}; 31
