* 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.
|
||
|
|
- interrupt-parent: should be the phandle for the interrupt controller
|
||
|
|
- 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>;
|
||
|
|
};
