-Device tree bindings for Domintech DMARD05, DMARD06, DMARD07 accelerometers
-
-Required properties:
- - compatible		: Should be "domintech,dmard05"
-				 or "domintech,dmard06"
-				 or "domintech,dmard07"
- - reg			: I2C address of the chip. Should be 0x1c
-
-Example:
-	&i2c1 {
-		/* ... */
-
-		accelerometer@1c {
-			compatible = "domintech,dmard06";
-			reg = <0x1c>;
-		};
-
-		/* ... */
-	};
