1 Freescale MX25 ADC/TSC MultiFunction Device (MFD)
2
3 This device combines two general purpose conversion queues one used for general
4 ADC and the other used for touchscreens.
5
6 Required properties:
7 - compatible: Should be "fsl,imx25-tsadc".
8 - reg: Start address and size of the memory area of
9 the device
10 - interrupts: Interrupt for this device
11 (See: ../interrupt-controller/interrupts.txt)
12 - clocks: An 'ipg' clock (See: ../clock/clock-bindings.txt)
13 - interrupt-controller: This device is an interrupt controller. It
14 controls the interrupts of both
15 conversion queues.
16 - #interrupt-cells: Should be '<1>'.
17 - #address-cells: Should be '<1>'.
18 - #size-cells: Should be '<1>'.
19
20 This device includes two conversion queues which can be added as subnodes.
21 The first queue is for the touchscreen, the second for general purpose ADC.

23 Example:
24 tscadc: tscadc@50030000 {
25 compatible = "fsl,imx25-tsadc";
26 reg = <0x50030000 0xc>;
27 interrupts = <46>;
28 clocks = <&clks 119>;
29 clock-names = "ipg";
30 interrupt-controller;
31 #interrupt-cells = <1>;
32 #address-cells = <1>;
33 #size-cells = <1>;
34 ranges;
35
36 tsc: tcq@50030400 {
37 compatible = "fsl,imx25-tcq";
38 reg = <0x50030400 0x60>;
39 ...
40 };
41
42 adc: gcq@50030800 {
43 compatible = "fsl,imx25-gcq";
44 reg = <0x50030800 0x60>;
45 ...
46 };
47 };
