* 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>;
};
