+description:
+  In MediaTek SoCs, the CIRQ is a low power interrupt controller designed to
+  work outside of MCUSYS which comprises with Cortex-Ax cores, CCI and GIC.
+  The external interrupts (outside MCUSYS) will feed through CIRQ and connect
+  to GIC in MCUSYS. When CIRQ is enabled, it will record the edge-sensitive
+  interrupts and generate a pulse signal to parent interrupt controller when
+  flush command is executed. With CIRQ, MCUSYS can be completely turned off
+  to improve the system power consumption without losing interrupts.
