   51) The "flipper" node
   6
   7  This node represents the multi-function "Flipper" chip, which packages
   8  many of the devices found in the Nintendo GameCube.
   9
  10  Required properties:
  11
  12   - compatible : Should be "nintendo,flipper"
  13
  141.a) The Video Interface (VI) node
  15
  16  Represents the interface between the graphics processor and a external
  17  video encoder.
  18
  19  Required properties:
  20
  21   - compatible : should be "nintendo,flipper-vi"
  22   - reg : should contain the VI registers location and length
  23   - interrupts : should contain the VI interrupt
  24
  251.b) The Processor Interface (PI) node
  26
  27  Represents the data and control interface between the main processor
  28  and graphics and audio processor.
  29
  30  Required properties:
  31
  32  - compatible : should be "nintendo,flipper-pi"
  33  - reg : should contain the PI registers location and length
  34
  351.b.i) The "Flipper" interrupt controller node
  36
  37  Represents the interrupt controller within the "Flipper" chip.
  38  The node for the "Flipper" interrupt controller must be placed under
  39  the PI node.
  40
  41  Required properties:
  42
  43  - compatible : should be "nintendo,flipper-pic"
  44
  451.c) The Digital Signal Procesor (DSP) node
  46

  53   - reg : should contain the DSP registers location and length
  54   - interrupts : should contain the DSP interrupt
  55
  561.c.i) The Auxiliary RAM (ARAM) node
  57
  58  Represents the non cpu-addressable ram designed mainly to store audio
  59  related information.
  60  The ARAM node must be placed under the DSP node.
  61
  62  Required properties:
  63
  64   - compatible : should be "nintendo,flipper-aram"
  65   - reg : should contain the ARAM start (zero-based) and length
  66
  671.d) The Disk Interface (DI) node
  68
  69  Represents the interface used to communicate with mass storage devices.
  70
  71  Required properties:
  72
  73   - compatible : should be "nintendo,flipper-di"
  74   - reg : should contain the DI registers location and length
