Subject: [PATCH v3 3/4] thermal: add more description for thermal-zones
Date: Mon, 25 Aug 2014 14:29:47 +0800 [thread overview]
Message-ID: <1408948188-4181-4-git-send-email-wni@nvidia.com> (raw)
In-Reply-To: <1408948188-4181-1-git-send-email-wni@nvidia.com>
Add more description for the "polling-delay" property.
Set "trips" and "cooling maps" as optional property, because
if missing these two sub-nodes, the thermal zone device still
work properly.
Signed-off-by: Wei Ni <wni@nvidia.com>
