=============================
|
|
|
|
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
|
|
|
|

|
|
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.
|
|
|
|

|
|
|
|
- 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
