From 88e20c74ee020f9e0c99dfce0dd9aa61c3f0cca0 Mon Sep 17 00:00:00 2001 From: Stefan Wahren Date: Tue, 27 Dec 2016 18:29:57 +0000 Subject: [PATCH] irqchip/mxs: Enable SKIP_SET_WAKE and MASK_ON_SUSPEND The ICOLL controller doesn't provide any facility to configure the wakeup sources. That's the reason why this implementation lacks the irq_set_wake implementation. But this prevent us from properly entering power management states like "suspend to idle". So enable the flags IRQCHIP_SKIP_SET_WAKE and IRQCHIP_MASK_ON_SUSPEND to let the irqchip core allows and handles the power management.
