-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>;
