From 77f827de07432a74821cf0f831d699544b2d474f Mon Sep 17 00:00:00 2001 From: "Rafael J. Wysocki" Date: Mon, 6 Aug 2012 01:39:57 +0200 Subject: PM / Domains: Add power off/on function for system core suspend stage Introduce function pm_genpd_syscore_switch() and two wrappers around it, pm_genpd_syscore_poweroff() and pm_genpd_syscore_poweron(), allowing the callers to let the generic PM domains framework know that the given device is not necessary any more and its PM domain can be turned off (the former) or that the given device will be required immediately, so its PM domain has to be turned on (the latter) during the system core (syscore) stage of system suspend (or hibernation) and resume. These functions will be used for handling devices registered as clock sources and clock event devices that belong to PM domains. Signed-off-by: Rafael J.
