+title: Kalray Coolidge SoC Interrupt Generator (ITGEN)
+
+description: |
+ The Interrupt Generator (ITGEN) is an interrupt controller block.
+ It's purpose is to convert IRQ lines coming from SoC peripherals into writes
+ on the AXI bus. The ITGEN intended purpose is to write into the APIC mailboxes.

+ - 1st cell is for the IRQ number
+ - 2nd cell is for the trigger type as defined dt-bindings/interrupt-controller/irq.h
