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> (raw)
In-Reply-To: <1568135676-9328-1-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.

Signed-off-by: Thara Gopinath <thara.gopinath@linaro.org>

v1->v2:
	- Changes ti incorporate the new format of
	get_performance_state_count.
