+STMicroelectronics Acceleration Sensors
+
+Required properties:
+
+ - compatible : value should be one of the following:
+ (a) "st,lsm330dlhc-accel" for accelerometer in LSM330DLHC
+ (b) "st,lis3dh" for accelerometer in LIS3DH
+ (c) "st,lsm330d-accel" for accelerometer in LSM330
+ (d) "st,lsm330dl-accel" for accelerometer in LSM330DL
+ (e) "st,lsm330dlc-accel" for accelerometer in LSM330DLC
+ (f) "st,lsm331dlh" for accelerometer in LSM331DLH
+ (g) "st,lsm303dl-accel" for accelerometer in LSM303DL
+ (h) "st,lsm303dlh-accel" for accelerometer in LSM303DLH
+ (i) "st,lsm303dlm-accel" for accelerometer in LSM303DLM
+ (j) "st,lsm330-accel" for accelerometer in LMS330
+
+ - reg : the I2C address of the accelerometer
+
+Optional properties:
+
+ - st,drdy-int-pin : redirect DRDY on pin INT1 (1) or pin INT2 (2) (u8)
+
+ - interrupts : Interrupt numbers for the ST accelerometers, as an array
+ in case the accelerometer have more interrupt lines:
+ <DataReady irq>,
+ <Event irq>;
+
+ - interrupt-names : Array of strings associated with the interrupt numbers
+
+Example:
+
+lsm330dlc_accel@19 {
+ compatible = "st,lsm330dlc-accel";
+ reg = <0x19>;
+
+ st,drdy-int-pin = /bits/ 8 <1>;
+ interrupt-parent = <&gpx0>;
+ interrupts= <0 0>, <1 0>;
+ interrupt-names = "event-int". "drdy-int";\
+};
