-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 at 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 at 50030400 {
-			compatible = "fsl,imx25-tcq";
-			reg = <0x50030400 0x60>;
-			...
-		};
-
-		adc: gcq at 50030800 {
-			compatible = "fsl,imx25-gcq";
-			reg = <0x50030800 0x60>;
-			...
-		};
-	};
