Subject: [PATCH 12/16] OPP: Extend dev_pm_opp_data with performance level
Date: Wed,  7 Jun 2023 14:46:24 +0200	[thread overview]
Message-ID: <20230607124628.157465-13-ulf.hansson@linaro.org> (raw)
In-Reply-To: <20230607124628.157465-1-ulf.hansson@linaro.org>

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