+title: NVIDIA Tegra20 Legacy Interrupt Controller
+

+
+description: >
+  All Tegra SoCs contain a legacy interrupt controller that routes interrupts to
+  the GIC, and also serves as a wakeup source. It is also referred to as
+  "ictlr", hence the name of the binding.
+
+  The HW block exposes a number of interrupt controllers, each implementing a
+  set of 32 interrupts.
+
+  Notes:
+    - Because this HW ultimately routes interrupts to the GIC, the
+      interrupt specifier must be that of the GIC.
+    - Only SPIs can use the ictlr as an interrupt parent. SGIs and PPIs
+      are explicitly forbidden.
