From 4c6ab2e4ab05111066c35ff37b6cb0f285242d30 Mon Sep 17 00:00:00 2001 From: =?UTF-8?q?C=C3=A9dric=20Le=20Goater?= Date: Mon, 9 Mar 2015 21:56:14 +0100 Subject: dts: add device tree nodes for the core temperatures MIME-Version: 1.0 Content-Type: text/plain; charset=UTF-8 Content-Transfer-Encoding: 8bit This patch simply adds sensors nodes for the core temperatures. It uses the core PIR as a resource identifier to fit in the sensor model. The device tree nodes use the new layout.
