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>;

Required properties:
- compatible : Should be "ti,tps65086".
- reg : I2C slave address.
- interrupt-parent : Phandle to the parent interrupt controller.
- interrupts : The interrupt line the device is connected to.
- interrupt-controller : Marks the device node as an interrupt controller.
- #interrupt-cells : The number of cells to describe an IRQ, should be 2.
The first cell is the IRQ number.
The second cell is the flags, encoded as trigger
masks from ../interrupt-controller/interrupts.txt.
- gpio-controller : Marks the device node as a GPIO Controller.
- #gpio-cells : Should be two. The first cell is the pin number and
the second cell is used to specify flags.

initialization data. Child nodes must be named
after their hardware counterparts: buck[1-6],
ldoa[1-3], swa1, swb[1-2], and vtt. Each child

the output needs to decay, default is for
the output to slew down.
