Subject: [PATCH v2 2/5] soc: qcom: rpmhpd: Introduce function to retrieve power domain performance state count
Date:   Tue, 10 Sep 2019 13:14:33 -0400
Message-Id: <1568135676-9328-3-git-send-email-thara.gopinath@linaro.org>

Precedence: bulk

Populate .get_performace_state_count in genpd ops to retrieve the count
of performance states supported by a rpmh power domain.
