Subject: [PATCH V2 14/30] drm/msm: Migrate to dev_pm_opp_set_config()
Date: Fri,  1 Jul 2022 13:50:09 +0530	[thread overview]
Message-ID: <31b74e43d3af263e1b943bca1dd3debe885521d8.1656660185.git.viresh.kumar@linaro.org> (raw)
In-Reply-To: <cover.1656660185.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.
