    1 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>;
   32                 #address-cells = <1>;
   33                 #size-cells = <1>;
   34                 ranges;
   35 
   36                 tsc: tcq@50030400 {
   37                         compatible = "fsl,imx25-tcq";
   38                         reg = <0x50030400 0x60>;
   39                         ...
   40                 };
   41 
   42                 adc: gcq@50030800 {
   43                         compatible = "fsl,imx25-gcq";
   44                         reg = <0x50030800 0x60>;
   45                         ...
   46                 };
   47         };
