Subject: [PATCH 09/13] opp: Implement dev_pm_opp_set_opp()
Date: Thu, 21 Jan 2021 16:47:49 +0530	[thread overview]
Message-ID: <7d62f63ac64e59ee3327789ff1bc9cebc2da6944.1611227342.git.viresh.kumar@linaro.org> (raw)
In-Reply-To: <cover.1611227342.git.viresh.kumar@linaro.org>

The new helper dev_pm_opp_set_opp() can be used for configuring the
devices for a particular OPP and can be used by different type of
devices, even the ones which don't change frequency (like power
domains).
