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 | ||
