Subject: [PATCH 1/7] PM / OPP: Add dev_pm_opp_get_of_node()
Date: Fri, 16 Mar 2018 09:38:18 +0530 [thread overview]
Message-ID: <20180316040824.21472-2-rnayak@codeaurora.org> (raw)
In-Reply-To: <20180316040824.21472-1-rnayak@codeaurora.org>
From: Viresh Kumar <viresh.kumar@linaro.org>
This adds a new helper to let the power domain drivers to access
opp->np, so that they can read platform specific properties from the
