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>;

			fsl,adc-refp = <MX25_ADC_REFP_INT>;

			fsl,adc-refn = <MX25_ADC_REFN_NGND>;

		};

	};

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>;

		interrupts = <0>;

		fsl,wires = <4>;

	};
