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.
22
-
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>;

-
#address-cells = <1>;

#size-cells = <1>;
