Message-ID: <1408948188-4181-4-git-send-email-wni@nvidia.com> Date: Mon, 25 Aug 2014 14:29:47 +0800 From: Wei Ni <wni@...dia.com> To: <edubezval@...il.com>, <khali@...ux-fr.org>, <linux@...ck-us.net>, <swarren@...dotorg.org> CC: <lm-sensors@...sensors.org>, <linux-tegra@...r.kernel.org>, <linux-kernel@...r.kernel.org>, Wei Ni <wni@...dia.com> Subject: [PATCH v3 3/4] thermal: add more description for thermal-zones 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.
