  2. Nintendo GameCube device tree
  3. =============================
  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"
  107.    - reg : should contain the EXI registers location and length
  108.    - interrupts : should contain the EXI interrupt
