Subject: [PATCH v6 2/4] ARM: tegra: Add soctherm and thermal zones to Tegra124 device tree
Date: Fri, 26 Sep 2014 12:43:11 +0300
Message-ID: <1411724593-4037-3-git-send-email-cyndis@kapsi.fi> (raw)
In-Reply-To: <1411724593-4037-1-git-send-email-cyndis@kapsi.fi>

From: Mikko Perttunen <mperttunen@nvidia.com>

This adds the soctherm thermal sensing and management unit to the
Tegra124 device tree along with the four thermal zones corresponding
to the four thermal sensors provided by soctherm.
