12 * IXP2000 GPIO in/out, edge/level detection for IRQs:
13 * IRQs are generated on Falling-edge, Rising-Edge, Level-low, Level-High
14 * or both Falling-edge and Rising-edge.
15 * This must be called *before* the corresponding IRQ is registerd.
16 * Use this instead of directly setting the GPIO registers.
17 * GPIOs may also be used as GPIOs (e.g. for emulating i2c/smb)
