+STMicroelectronics Pressure Sensors
+
+Required properties:
+
+ - compatible : value should be:
+ (a) "st,lps331ap" for barometer in LPS331AP
+ (b) "st,lps001wp" for barometer in LPS001WP
+
+ - reg : the I2C address of the barometer
+
+Optional properties:
+
+ - st,drdy-int-pin : redirect DRDY on pin INT1 (1) or pin INT2 (2) (u8)
+
+ - interrupts : Interrupt numbers for the ST barometer, as an array
+ in case the barometer have more interrupt lines:
+ <DataReady irq>,
+ <Event irq>;
+
+ - interrupt-names : Array of strings associated with the interrupt numbers
+
+ - vdd-supply: Phandle to the Vdd supply regulator
+
+ - vddio-supply: Phandle to the Vdd-IO supply regulator
+
+Example:
+
+lps331ap5d@5d {
+ compatible = "st,lps331ap";
+ reg = <0x5d>;
+
+ st,drdy-int-pin = /bits/ 8 <1>;
+ interrupt-parent = <&gpf0>;
+ interrupts = <5 0>, <6 0>;
+ interrupt-names = "drdy-int", "event-int";
+ vdd-supply = <&ab8500_ldo_aux1_reg>;
+ vddio-supply = <&db8500_vsmps2_reg>;
+};
