Subject: [Patch v4 2/7] soc: qcom: rpmhpd: Introduce function to retrieve power domain performance state count
Date: Wed, 20 Nov 2019 07:56:28 -0500	[thread overview]
Message-ID: <1574254593-16078-3-git-send-email-thara.gopinath@linaro.org> (raw)
In-Reply-To: <1574254593-16078-1-git-send-email-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.
