Subject: [PATCH 4/4] ARM: dts: exynos4: Add CPU topology data
Date: Fri, 18 Apr 2014 16:43:01 +0200	[thread overview]
Message-ID: <1397832181-5153-5-git-send-email-t.figa@samsung.com> (raw)
In-Reply-To: <1397832181-5153-1-git-send-email-t.figa@samsung.com>

After fixing non-banked GIC support in GIC driver, CPU nodes can be
safely added to Exynos4 device tree sources, along with appropriate
gic-offset properties.
