-Nintendo GameCube device tree
-=============================
-
-1) The "flipper" node
-
- This node represents the multi-function "Flipper" chip, which packages
- many of the devices found in the Nintendo GameCube.
-
- Required properties:
-
- - compatible : Should be "nintendo,flipper"
-
-1.a) The Video Interface (VI) node
-
- Represents the interface between the graphics processor and a external
- video encoder.
-
- Required properties:
-
- - compatible : should be "nintendo,flipper-vi"
- - reg : should contain the VI registers location and length
- - interrupts : should contain the VI interrupt
-
-1.b) The Processor Interface (PI) node
-
- Represents the data and control interface between the main processor
- and graphics and audio processor.
-
- Required properties:
-
- - compatible : should be "nintendo,flipper-pi"
- - reg : should contain the PI registers location and length
-
-1.b.i) The "Flipper" interrupt controller node
-
- Represents the interrupt controller within the "Flipper" chip.
- The node for the "Flipper" interrupt controller must be placed under
- the PI node.
-
- Required properties:
-
- - compatible : should be "nintendo,flipper-pic"
-
-1.c) The Digital Signal Procesor (DSP) node
-
- Represents the digital signal processor interface, designed to offload
- audio related tasks.
-
- Required properties:
-
- - compatible : should be "nintendo,flipper-dsp"
- - reg : should contain the DSP registers location and length
- - interrupts : should contain the DSP interrupt
-
-1.c.i) The Auxiliary RAM (ARAM) node
-
- Represents the non cpu-addressable ram designed mainly to store audio
- related information.
- The ARAM node must be placed under the DSP node.
-
- Required properties:
-
- - compatible : should be "nintendo,flipper-aram"
- - reg : should contain the ARAM start (zero-based) and length
-
-1.d) The Disk Interface (DI) node
-
- Represents the interface used to communicate with mass storage devices.
-
- Required properties:
-
- - compatible : should be "nintendo,flipper-di"
- - reg : should contain the DI registers location and length
- - interrupts : should contain the DI interrupt
-
-1.e) The Audio Interface (AI) node
-
- Represents the interface to the external 16-bit stereo digital-to-analog
- converter.
-
- Required properties:
-
- - compatible : should be "nintendo,flipper-ai"
- - reg : should contain the AI registers location and length
- - interrupts : should contain the AI interrupt
-
-1.f) The Serial Interface (SI) node
-
- Represents the interface to the four single bit serial interfaces.
- The SI is a proprietary serial interface used normally to control gamepads.
- It's NOT a RS232-type interface.
-
- Required properties:
-
- - compatible : should be "nintendo,flipper-si"
- - reg : should contain the SI registers location and length
- - interrupts : should contain the SI interrupt
-
-1.g) The External Interface (EXI) node
-
- Represents the multi-channel SPI-like interface.
-
- Required properties:
-
- - compatible : should be "nintendo,flipper-exi"
- - reg : should contain the EXI registers location and length
- - interrupts : should contain the EXI interrupt
-
