Date: Tue, 5 Aug 2014 11:12:58 +0300 From: Mikko Perttunen <mperttunen@...dia.com> To: <swarren@...dotorg.org>, <thierry.reding@...il.com> CC: <linux-kernel@...r.kernel.org>, <linux-arm-kernel@...ts.infradead.org>, <linux-tegra@...r.kernel.org>, Mikko Perttunen <mperttunen@...dia.com> Subject: [PATCH 1/3] of: Add descriptions of thermtrip properties to Tegra PMC bindings Hardware-triggered thermal reset requires configuring the I2C reset procedure. This configuration is read from the device tree, so document the relevant properties in the binding documentation.
