Subject: [PATCH 12/17] ARM: dts: qcom: add opp table for cpu and l2 for ipq8064
Date:   Tue, 18 Jan 2022 02:20:42 +0100
Message-Id: <20220118012051.21691-13-ansuelsmth@gmail.com>
In-Reply-To: <20220118012051.21691-1-ansuelsmth@gmail.com>
References: <20220118012051.21691-1-ansuelsmth@gmail.com>
MIME-Version: 1.0
Content-Transfer-Encoding: 8bit
Precedence: bulk

Add opp table for cpu and l2 cache. The l2 cache won't work as it would
require a dedicated cpufreq driver to scale cache with core.

Opp-level is set based on the logic of
0: idle level
1: normal level
2: turbo level
