Subject: [Patch v5 2/6] soc: qcom: rpmhpd: Introduce function to retrieve power domain performance state count
Date: Thu, 19 Mar 2020 21:41:03 -0400	[thread overview]
Message-ID: <20200320014107.26087-3-thara.gopinath@linaro.org> (raw)
In-Reply-To: <20200320014107.26087-1-thara.gopinath@linaro.org>

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