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>;
...
};
};
