  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
 141.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
 251.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
 351.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
 451.c) The Digital Signal Procesor (DSP) node
 46
