Subject: [PATCH v3 13/18] ARM: dts: qcom: add opp table for cpu and l2 for ipq8064
Date:   Wed,  9 Mar 2022 20:01:47 +0100
Message-Id: <20220309190152.7998-14-ansuelsmth@gmail.com>
In-Reply-To: <20220309190152.7998-1-ansuelsmth@gmail.com>

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
