Subject: [PATCH v5 09/27] irqchip/gic: Lower priority of GIC interrupts
Date: Tue, 28 Aug 2018 16:51:19 +0100 [thread overview]
Message-ID: <1535471497-38854-10-git-send-email-julien.thierry@arm.com> (raw)
In-Reply-To: <1535471497-38854-1-git-send-email-julien.thierry@arm.com>
The current value used for IRQ priorities is high among the
non-secure interrupt priority values.
Lower the default priority of interrupts so there is more flexibility
to define higher priority interrupts.
