| 9 | description: | |
| 10 | UniPhier AIDET (ARM Interrupt Detector) is an add-on block for ARM GIC |
| 11 | (Generic Interrupt Controller). GIC itself can handle only high level and |
| 12 | rising edge interrupts. The AIDET provides logic inverter to support low |
| 13 | level and falling edge interrupts. |
