-mx25 touchscreen conversion queue module which controls the ADC unit of the
-mx25 for attached touchscreens.
-
-Required properties:
- - compatible: Should be "fsl,imx25-tcq".
- - reg: Memory range of the device.
- - interrupts: Should be the interrupt number associated with this module within
-   the tscadc unit (<0>).
- - fsl,wires: Should be '<4>' or '<5>'
-
-Optional properties:
- - fsl,pen-debounce-ns: Pen debounce time in nanoseconds.
- - fsl,pen-threshold: Pen-down threshold for the touchscreen. This is a value
-   between 1 and 4096. It is the ratio between the internal reference voltage
-   and the measured voltage after the plate was precharged. Resistance between
-   plates and therefore the voltage decreases with pressure so that a smaller
-   value is equivalent to a higher pressure.
- - fsl,settling-time-ns: Settling time in nanoseconds. The settling time is before
-   the actual touch detection to wait for an even charge distribution in the
-   plate.
-
-This device includes two conversion queues which can be added as subnodes.
-The first queue is for the touchscreen, the second for general purpose ADC.
-
-Example:
-	tsc: tcq at 50030400 {
-		compatible = "fsl,imx25-tcq";
-		reg = <0x50030400 0x60>;
-		interrupt-parent = <&tscadc>;
-		interrupts = <0>;
-		fsl,wires = <4>;
-	};
