+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.
