Subject: [PATCH] ARM: dts: vexpress: Add CCI node to TC2 device-tree
Date: Fri, 30 Aug 2013 15:26:00 +0100	[thread overview]
Message-ID: <1377872760.3655.48.camel@linaro1.home> (raw)

The Versatile Express V2P-CA15_A7 (aka TC2) has a CCI-400 which is
needed to get Multi-Cluster Power Management (MCPM) working.

Signed-off-by: Jon Medhurst <tixy@linaro.org>

I was unsure if the devicetree list should be cc'd when making use of
already agreed and documented bindings, so I erred on the side of
caution and added it. Please say if this is unnecessary noise, or is
expected for all device-tree changes, thanks.
