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