Subject: [PATCHv3 04/15] Thermal: Add platform level information to thermal.h
Date: Sat, 1 Sep 2012 17:21:25 +0530 [thread overview]
Message-ID: <1346500296-25200-5-git-send-email-durgadoss.r@intel.com> (raw)
In-Reply-To: <1346500296-25200-1-git-send-email-durgadoss.r@intel.com>
This patch adds platform level information to thermal.h
by introducing two structures to hold:
* bind parameters for a thermal zone,
* zone level platform parameters
