Subject: [PATCH 4/9] OPP: Extend dev_pm_opp_data with a level
Date:   Mon, 25 Sep 2023 15:17:10 +0200
Message-Id: <20230925131715.138411-5-ulf.hansson@linaro.org>

Let's extend the dev_pm_opp_data with a level variable, to allow users to
specify a corresponding level (performance state) for a dynamically added
OPP.
