   4
   5 1) 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
  14 1.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
  25 1.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
  35 1.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
  45 1.c) The Digital Signal Procesor (DSP) node
  46
  47   Represents the digital signal processor interface, designed to offload
  48   audio related tasks.
  49
  50   Required properties:
  51
  52    - compatible : should be "nintendo,flipper-dsp"
  53    - reg : should contain the DSP registers location and length
  54    - interrupts : should contain the DSP interrupt
  55
  56 1.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
  67 1.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
  75    - interrupts : should contain the DI interrupt
  76
  77 1.e) The Audio Interface (AI) node
  78
  79   Represents the interface to the external 16-bit stereo digital-to-analog
  80   converter.
  81
  82   Required properties:
  83
  84    - compatible : should be "nintendo,flipper-ai"
  85    - reg : should contain the AI registers location and length
  86    - interrupts : should contain the AI interrupt
  87
  88 1.f) The Serial Interface (SI) node
  89
  90   Represents the interface to the four single bit serial interfaces.
  91   The SI is a proprietary serial interface used normally to control gamepads.
  92   It's NOT a RS232-type interface.
  93
  94   Required properties:
  95
  96    - compatible : should be "nintendo,flipper-si"
  97    - reg : should contain the SI registers location and length
  98    - interrupts : should contain the SI interrupt
  99
 100 1.g) The External Interface (EXI) node
 101
 102   Represents the multi-channel SPI-like interface.
 103
 104   Required properties:
 105
 106    - compatible : should be "nintendo,flipper-exi"
