Subject: [PATCH 7/7] ARM: OMAP4+: PM: Use only valid low power state for CPU hotplug
Date: Fri, 22 Aug 2014 08:49:33 -0500 [thread overview]
Message-ID: <1408715373-25791-8-git-send-email-nm@ti.com> (raw)
In-Reply-To: <1408715373-25791-1-git-send-email-nm@ti.com>
Not all SoCs support OFF mode - for example DRA74/72. So, use valid
power state during CPU hotplug.
