Subject: [PATCH 3/4] PM / Domains: Remove pm_genpd_poweron() API
Date: Tue, 6 Oct 2015 14:27:51 +0200 [thread overview]
Message-ID: <1444134471-17979-1-git-send-email-ulf.hansson@linaro.org> (raw)
Once genpd could be configured to be built with CONFIG_PM_RUNTIME unset
(nowadays CONFIG_PM), the pm_genpd_poweron() API served a purpose, since
it allowed users to power on a PM domain.
As such configuration no longer is supported, users shall solely rely on
using some of the runtime PM APIs to power on a PM domain.
