+* HTS221 STM humidity + temperature sensor
+
+Required properties:
+- compatible: should be "st,hts221"
+- reg: i2c address of the sensor / spi cs line
+
+Optional properties:
+- interrupts: interrupt mapping for GPIO IRQ. It should be configured with
+ flags IRQ_TYPE_LEVEL_HIGH or IRQ_TYPE_EDGE_RISING
+- interrupt-parent: should be the phandle for the interrupt controller
+
+Example:
+
+hts221@5f {
+ compatible = "st,hts221";
+ reg = <0x5f>;
+ interrupt-parent = <&gpio0>;
+ interrupts = <0 IRQ_TYPE_EDGE_RISING>;
+};
