Subject: [PATCHv3 13/16] cpuidle: mvebu: add Armada 38x support
Date: Wed, 23 Jul 2014 15:00:50 +0200 [thread overview]
Message-ID: <1406120453-29291-14-git-send-email-thomas.petazzoni@free-electrons.com> (raw)
In-Reply-To: <1406120453-29291-1-git-send-email-thomas.petazzoni@free-electrons.com>
This commit adds the list of cpuidle states supported by the Armada
38x SoC in the cpuidle-mvebu-v7 driver, as well as the necessary logic
around it to support this SoC.
