3 mx25 touchscreen conversion queue module which
4 mx25 for attached touchscreens.

6 Required properties:
7 - compatible: Should be "fsl,imx25-tcq".
8 - reg: Memory range of the device.
9 - interrupts: Should be the interrupt number
10 the tscadc unit (<0>).
11 - fsl,wires: Should be '<4>' or '<5>'
12
13 Optional properties:
14 - fsl,pen-debounce-ns: Pen debounce time in n
15 - fsl,pen-threshold: Pen-down threshold for t
16 between 1 and 4096. It is the ratio between
17 and the measured voltage after the plate wa
18 plates and therefore the voltage decreases
19 value is equivalent to a higher pressure.
20 - fsl,settling-time-ns: Settling time in nano
21 the actual touch detection to wait for an e
22 plate.

29 compatible = "fsl,imx25-tcq";
30 reg = <0x50030400 0x60>;
31 interrupt-parent = <&tscadc>;
32 interrupts = <0>;
33 fsl,wires = <4>;
