+Subject: [PATCH v3 13/18] ARM: dts: qcom: add opp table for cpu and l2 for
+ ipq8064
+
+Add opp table for cpu and l2 cache. While the current cpufreq is
+the generic one that doesn't scale the L2 cache, we add the l2
+cache opp anyway for the sake of completeness. This will be handy in the
+future when a dedicated cpufreq driver is introduced for krait cores
+that will correctly scale l2 cache with the core freq.
+
+Opp-level is set based on the logic of
+0: idle level
+1: normal level
+2: turbo level
