+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.
