Subject: [PATCH] arm64: dts: Add L2 cache node to msm8916
Date: Fri,  8 Jan 2016 15:57:09 -0800	[thread overview]
Message-ID: <1452297429-6382-1-git-send-email-sboyd@codeaurora.org> (raw)

The msm8916 SoC has an L2 cache for all 4 CPUs. Add it to the
dtsi file so that the cache hierarchy can be probed.
