Subject: [PATCH RESEND v1 5/5] irqchip/gic-v3: Allow interrupt to be configured as wake-up sources
Date:   Fri, 17 Aug 2018 13:10:26 -0600
Message-Id: <20180817191026.32245-6-ilina@codeaurora.org>
In-Reply-To: <20180817191026.32245-1-ilina@codeaurora.org>

From: Marc Zyngier <marc.zyngier@arm.com>

Although GICv3 doesn't directly offers support for wake-up interrupts
and relies on external HW for this, it shouldn't prevent the driver
for such HW from doing it work.

Let's set the required flags on the irq_chip structures.
