+* Bosch BMA180 / BMA250 triaxial acceleration sensor
+
+http://omapworld.com/BMA180_111_1002839.pdf
+http://ae-bst.resource.bosch.com/media/products/dokumente/bma250/bst-bma250-ds002-05.pdf
+
+Required properties:
+
+  - compatible : should be "bosch,bma180" or "bosch,bma250"
+  - reg : the I2C address of the sensor
+
+Optional properties:
+
+  - interrupts : interrupt mapping for GPIO IRQ, it should by configured with
+		flags IRQ_TYPE_LEVEL_HIGH | IRQ_TYPE_EDGE_RISING
+		For the bma250 the first interrupt listed must be the one
+		connected to the INT1 pin, the second (optional) interrupt
+		listed must be the one connected to the INT2 pin.
+
+Example:
+
+bma180@40 {
+	compatible = "bosch,bma180";
+	reg = <0x40>;
+	interrupt-parent = <&gpio6>;
+	interrupts = <18 (IRQ_TYPE_LEVEL_HIGH | IRQ_TYPE_EDGE_RISING)>;
+};
