   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>'.

  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.
