Subject: [PATCH 09/31] cpufreq: ti: Migrate to dev_pm_opp_set_config()
Date:   Thu, 26 May 2022 17:12:08 +0530
Message-Id: <b056e9069840a52fa28c80e4f10f0b440e6c3206.1653564321.git.viresh.kumar@linaro.org>

The OPP core now provides a unified API for setting all configuration
types, i.e. dev_pm_opp_set_config().

Lets start using it.
