Freescale MX25 ADC/TSC MultiFunction Device (MFD)
|
|
|
|
This device combines two general purpose conversion queues one used for general
|
|
ADC and the other used for touchscreens.
|
|
|
|
Required properties:
|
|
- compatible: Should be "fsl,imx25-tsadc".
|
|
- reg: Start address and size of the memory area of
|
|
the device
|
|
- interrupts: Interrupt for this device
|
|
(See: ../interrupt-controller/interrupts.txt)
|
|
- clocks: An 'ipg' clock (See: ../clock/clock-bindings.txt)
|
|
- interrupt-controller: This device is an interrupt controller. It
|
|
controls the interrupts of both
|
|
conversion queues.
|
|
- #interrupt-cells: Should be '<1>'.
|
|
- #address-cells: Should be '<1>'.
|
|
- #size-cells: Should be '<1>'.
|
|
|
|
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:
|
|
tscadc: tscadc@50030000 {
|
|
compatible = "fsl,imx25-tsadc";
|
|
reg = <0x50030000 0xc>;
|
|
interrupts = <46>;
|
|
clocks = <&clks 119>;
|
|
clock-names = "ipg";
|
|
interrupt-controller;
|
|
#interrupt-cells = <1>;
|
|
#address-cells = <1>;
|
|
#size-cells = <1>;
|
|
ranges;
|
|
|
|
tsc: tcq@50030400 {
|
|
compatible = "fsl,imx25-tcq";
|
|
reg = <0x50030400 0x60>;
|
|
...
|
|
};
|
|
|
|
adc: gcq@50030800 {
|
|
compatible = "fsl,imx25-gcq";
|
|
reg = <0x50030800 0x60>;
|
|
...
|
|
};
|
|
};
