+Atmel qt1070 keyboard interface
+
+Required Properties:
+- compatible: Should be "atmel,qt1070"
+- reg: I2C slave address
+- interrupt-parent: Depends on SoC
+- interrupts: The interrupt pin number to the cpu, and trigger mode.
+
+Example:
+
+ qt1070@1b {
+ compatible = "atmel,qt1070";
+ reg = <0x1b>;
+ interrupt-parent = <&pioA>;
+ interrupts = <7 0x0>;
+ };
