Subject: [PATCH 6/6] arm64: dts: Add CPU topology properties for ARMv8 4xA53 4xA57 FVP
Date: Wed, 11 Dec 2013 13:13:26 +0000 [thread overview]
Message-ID: <1386767606-6391-6-git-send-email-broonie@kernel.org> (raw)
In-Reply-To: <1386767606-6391-1-git-send-email-broonie@kernel.org>
From: Mark Brown <broonie@linaro.org>
This provides for discovery of the clusters using the CPU topology
bindings, it is added as a separate commit to aid testing of the code
for systems without explicit topology bindings.
Signed-off-by: Mark Brown <broonie@linaro.org>
