irqchip/bcm7120-l2: Set controller as wake-up source (f4ccb745) · Commits · 戴 / test

Utilize the Broadcom interrupt controller standard property "brcm,irq-can-wake" to flag whether this particular interrupt controller instance is wake-up capable. Since we do not know what type of parent interrupt controller we are interfaced with, ensure that enable_irq_wake() is called early on. Signed-off-by:
