| 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 | ||
