+* STMicroelectronics LPS331AP barometer sensor
+
+Required properties:
+
+ - compatible : should be "lps331ap"
+ - reg : the I2C address of the barometer
+
+Optional properties:
+
+ - drdy-int-pin : redirect DRDY on pin INT1 (1) or pin INT2 (2) (u8)
+ - interrupt-parent : phandle to the interrupt map subnode
+ - interrupts : interrupt mapping for LPS331AP interrupt sources:
+ 2 sources: 0 - INT1, 1 - INT2
+ - irq-map : irq sub-node defining interrupt map
+ (all properties listed below are required):
+ - #interrupt-cells : should be 1
+ - #address-cells : should be 0
+ - #size-cells : should be 0
+ - interrupt-map : table of entries consisting of three child elements:
+ - unit_interrupt_specifier - 0 : INT1, 1 : INT2
+ - interrupt parent phandle
+ - parent unit interrupt specifier consisiting of two elements:
+ - index of the interrupt within the controller
+ - flags : should be 0
+
+Example:
+
+lps331ap@5d {
+ compatible = "lps331ap";
+ reg = <0x5d>;
+ drdy-int-pin = /bits/ 8 <2>;
+ interrupt-parent = <&irq_map>;
+ interrupts = <0>, <1>;
+
+ irq_map: irq-map {
+ #interrupt-cells = <1>;
+ #address-cells = <0>;
+ #size-cells = <0>;
+ interrupt-map = <0 &gpf0 5 0>;
+ };
+};
