ImgTec Powerdown Controller (PDC) Interrupt Controller has a number of input
|
|
interrupt lines which can wake the system, and are passed on through output
|
|
interrupt lines.

<1st-cell>: The interrupt-number that identifies the interrupt source.

<2nd-cell>: The level-sense information, encoded using the Linux interrupt

flags as follows (only 4 valid for peripheral interrupts):
|
|
0 = none (decided by software)

1 = low-to-high edge triggered

2 = high-to-low edge triggered
|

3 = both edge triggered
