config MTK_SYS_CIRQ bool "sys cirq" help System interrupt controller(SYS_CIRQ) is a low-power interrupt controller which is designed to work outside MCUSYS as second level interrupt controller. With SYS_CIRQ, the MCUSYS can be completely turned off to improve system power consumption without losing interrupts. config FAST_CIRQ_CLONE_FLUSH bool "fast cirq clone flush" depends on MTK_SYS_CIRQ help Legacy CIRQ driver clone and flush IRQ pol/sen/pending very slow, since it checks every IRQ to decide if it should clone or not. This config speed up the process by only clone once when the sysetm first enter low power mode. and only setup cirq IDs for wakeup source.
