18c2ecf20Sopenharmony_ci* HTS221 STM humidity + temperature sensor 28c2ecf20Sopenharmony_ci 38c2ecf20Sopenharmony_ciRequired properties: 48c2ecf20Sopenharmony_ci- compatible: should be "st,hts221" 58c2ecf20Sopenharmony_ci- reg: i2c address of the sensor / spi cs line 68c2ecf20Sopenharmony_ci 78c2ecf20Sopenharmony_ciOptional properties: 88c2ecf20Sopenharmony_ci- drive-open-drain: the interrupt/data ready line will be configured 98c2ecf20Sopenharmony_ci as open drain, which is useful if several sensors share the same 108c2ecf20Sopenharmony_ci interrupt line. This is a boolean property. 118c2ecf20Sopenharmony_ci If the requested interrupt is configured as IRQ_TYPE_LEVEL_HIGH or 128c2ecf20Sopenharmony_ci IRQ_TYPE_EDGE_RISING a pull-down resistor is needed to drive the line 138c2ecf20Sopenharmony_ci when it is not active, whereas a pull-up one is needed when interrupt 148c2ecf20Sopenharmony_ci line is configured as IRQ_TYPE_LEVEL_LOW or IRQ_TYPE_EDGE_FALLING. 158c2ecf20Sopenharmony_ci Refer to pinctrl/pinctrl-bindings.txt for the property description. 168c2ecf20Sopenharmony_ci- interrupts: interrupt mapping for IRQ. It should be configured with 178c2ecf20Sopenharmony_ci flags IRQ_TYPE_LEVEL_HIGH, IRQ_TYPE_EDGE_RISING, IRQ_TYPE_LEVEL_LOW or 188c2ecf20Sopenharmony_ci IRQ_TYPE_EDGE_FALLING. 198c2ecf20Sopenharmony_ci 208c2ecf20Sopenharmony_ci Refer to interrupt-controller/interrupts.txt for generic interrupt 218c2ecf20Sopenharmony_ci client node bindings. 228c2ecf20Sopenharmony_ci 238c2ecf20Sopenharmony_ciExample: 248c2ecf20Sopenharmony_ci 258c2ecf20Sopenharmony_cihts221@5f { 268c2ecf20Sopenharmony_ci compatible = "st,hts221"; 278c2ecf20Sopenharmony_ci reg = <0x5f>; 288c2ecf20Sopenharmony_ci interrupt-parent = <&gpio0>; 298c2ecf20Sopenharmony_ci interrupts = <0 IRQ_TYPE_EDGE_RISING>; 308c2ecf20Sopenharmony_ci}; 31
