Documentation/devicetree/bindings/iio/adc/fsl,imx25-gcq.txt

+Freescale i.MX25 ADC GCQ device
+
+This is a generic conversion queue device that can convert any of the
+analog inputs using the ADC unit of the i.MX25.
+
+Required properties:
+ - compatible: Should be "fsl,imx25-gcq".
+ - reg: Should be the register range of the module.
+ - interrupts: Should be the interrupt number of the module.
+   Typically this is <1>.
+ - interrupt-parent: phandle to the tsadc module of the i.MX25.
+ - #address-cells: Should be <1> (setting for the subnodes)
+ - #size-cells: Should be <0> (setting for the subnodes)
+
+Optional properties:
+ - vref-ext-supply: The regulator supplying the ADC reference voltage.
+   Required when at least one subnode uses the this reference.
+ - vref-xp-supply: The regulator supplying the ADC reference voltage on pin XP.
+   Required when at least one subnode uses this reference.
+ - vref-yp-supply: The regulator supplying the ADC reference voltage on pin YP.
+   Required when at least one subnode uses this reference.
+
+Sub-nodes:
+Optionally you can define subnodes which define the reference voltage
+for the analog inputs.
+
+Required properties for subnodes:
+ - reg: Should be the number of the analog input.
+     0: xp
+     1: yp
+     2: xn
+     3: yn
+     4: wiper
+     5: inaux0
+     6: inaux1
+     7: inaux2
+Optional properties for subnodes:
+ - fsl,adc-refp: specifies the positive reference input as defined in
+     <dt-bindings/iio/adc/fsl-imx25-gcq.h>
+ - fsl,adc-refn: specifies the negative reference input as defined in
+     <dt-bindings/iio/adc/fsl-imx25-gcq.h>
+
+Example:
+
+	adc: adc@50030800 {
+		compatible = "fsl,imx25-gcq";
+		reg = <0x50030800 0x60>;
+		interrupt-parent = <&tscadc>;
+		interrupts = <1>;
+		#address-cells = <1>;
+		#size-cells = <0>;
+
+		inaux@5 {
+			reg = <5>;

Documentation/devicetree/bindings/input/touchscreen/fsl-mx25-tcq.txt

+Freescale mx25 TS conversion queue module
+
+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>).
+ - interrupt-parent: Should be a phandle to the tscadc unit.
+ - 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. Resistence 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@50030400 {
+		compatible = "fsl,imx25-tcq";
+		reg = <0x50030400 0x60>;
+		interrupt-parent = <&tscadc>;
