Subject: [PATCH v4 05/26] irqchip/gic: Unify GIC priority definitions
Date: Fri, 25 May 2018 10:49:11 +0100 [thread overview]
Message-ID: <1527241772-48007-6-git-send-email-julien.thierry@arm.com> (raw)
In-Reply-To: <1527241772-48007-1-git-send-email-julien.thierry@arm.com>
LPIs use the same priority value as other GIC interrupts.
Make the GIC default priority definition visible to ITS implementation
and use this same definition for LPI priorities.
