   4 Subject: [PATCH v3 13/18] ARM: dts: qcom: add opp table for cpu and l2 for
   5  ipq8064
   6
   7 Add opp table for cpu and l2 cache. While the current cpufreq is
   8 the generic one that doesn't scale the L2 cache, we add the l2
   9 cache opp anyway for the sake of completeness. This will be handy in the
  10 future when a dedicated cpufreq driver is introduced for krait cores
  11 that will correctly scale l2 cache with the core freq.
  12
  13 Opp-level is set based on the logic of
  14 0: idle level
  15 1: normal level
  16 2: turbo level
