Subject: [RFC part2 PATCH 6/9] Irqchip / gic: Set as default domain so we can access from ACPI
Date: Wed, 4 Dec 2013 00:39:10 +0800 [thread overview]
Message-ID: <1386088753-2850-7-git-send-email-hanjun.guo@linaro.org> (raw)
In-Reply-To: <1386088753-2850-1-git-send-email-hanjun.guo@linaro.org>
If we set the GIC as the default domain then we can access it for IRQ
mapping within the ACPI code.
