* Freescale i.MX28 LRADC device driver

Required properties:
- compatible: Should be "fsl,imx28-lradc"
- reg: Address and length of the register set for the device
- interrupts: Should contain the LRADC interrupts

Optional properties:
- fsl,lradc-touchscreen-wires: Number of wires used to connect the touchscreen
                               to LRADC. Valid value is either 4 or 5. If this
                               property is not present, then the touchscreen is
                               disabled.

Examples:

	lradc@80050000 {
		compatible = "fsl,imx28-lradc";
		reg = <0x80050000 0x2000>;
		interrupts = <10 14 15 16 17 18 19
				20 21 22 23 24 25>;
	};
